The study of new semiconducting materials, high temperature superconductors, photovoltaic devices, and organic electronic materials typically requires low-level sourcing and measurement because the materials are often nanostructures. The trouble is, the types of low-level measurements required to fully characterize such small structures are often contaminated with significant levels of power line, thermal, and other types of ambient noise signals. This technical note, "A New Approach to Improving Confidence in Low-Level Measurements of Nanostructures," examines existing methods and how well they address the challenge of noise in measurement. It also provides an in-depth look at a solution: a synchronized and modular AC + DC sourcing and measurement system that utilizes optimum sensitivity, noise rejection, and uninterrupted data acquisition to more confidently characterize such structures.

External noise, also known as interference, introduces measurement error into instrument setups. For numerous research and industrial applications, high measurement precision is required. However, the complex function of external noise often makes it difficult to understand and mitigate. This guide, “A Practical Approach to Understanding External Noise,” provides a start. It examines the different types of noise (external vs. intrinsic noise), discusses the impact on measurements, looks at common types of coupling and major sources of external noise, and offers possible strategies for mitigating the effects of external noise.

Studying quantum materials not only offers a path for developing new technologies but also provides a platform to advance scientific understanding. In this application note, we demonstrated the use of the M81-SSM system to obtain a Landau fan using a bilayer graphene sample and performed the canonical data analysis, converting gate voltage to carrier density, extracting energy states degeneracies, and determining mobility. https://hubs.li/Q02nShMT0 #Quantum #HallEffect #Characterization #Nanomaterials

🍎 Hello research students! We are thrilled to present an educational webinar series about common practices and techniques for device and material research. This educational series will be divided into 3 webinars: 1️⃣ How to Select a Lock-in Amplifier 2️⃣ How to Optimize Electrical Measurements of Nanomaterials 3️⃣ How to Handle Phase Shifts in a Measurement In our 1st webinar, we will discuss the world of lock-in amplifiers, focusing on how to select the right one and what key specifications to consider. Presented by Nadia Dugan, Lake Shore's Product Marketer, this session is designed for beginners and those with intermediate knowledge of lock-in amplifiers. 💡 In this webinar we will: 🔹 Cover the importance of choosing the right lock-in 🔹 Dive into the various types of lock-in amplifiers available 🔹 Discuss practical insights into lock-in noise calculations 🔹 Examine the impact of cable capacitance, device resistance, and frequency on lock-in measurements 📹 Register for the How to Select a Lock-in webinar: https://hubs.li/Q02JM3Jr0 #LockInAmplifier #MaterialsScience #DeviceResearch #AdvancingResearch #Research

We are excited to congratulate our founder, John Swartz, on the publication of his new book, "The History of Steamboats on Findley Lake: In the Town of Mina, Chautauqua County, New York." He celebrated the book's release with a book signing at the recent 2024 Town of Mina Bicentennial Celebration, where both John and wife, Helen, served as the Grand Marshals of the parade. Findley Lake is where John was born, and his book chronicles the various paddle steamboats that operated on the lake from the 1870s to the 1920s, including one owned by his grandfather and great uncle. Also worth noting: The "Lake Shore" in our company's name pays homage to his years of growing up on the shores of Findley Lake.

We are thrilled to be at SPIE, the international society for optics and photonics. Join us at 📍 Booth 409 to learn about our TTPX cryogenic probe station. The TTPX is our premium station design for electro-optical material characterization. It supports optional backside optical illumination of a sample, which is ideal for examining photosensitive materials with topside metallization. We also offer a wide range of stations for photovoltaic material and semiconductor optoelectronic device R&D, including configurations available for electro-optical, DC, RF, and microwave measurements, temperatures as low as 1.6 K, integrated magnetic field, and cryogen-free operation. #SPIEOpticsPhotonics #Optics #Photonics

Save the 📆 date! Choosing the right cryostat can be a challenge, especially when considering your long-term needs and budgetary requirements. This webinar provides a comprehensive overview of the key factors to consider when evaluating cryostats for a research lab, including: 🔹Temperature stability and range, including the need for high temperature 🔹Types of cooling mechanisms, and their advantages and drawbacks 🔹Sample considerations, including the environment and vibration sensitivity 🔹Application and measurement requirements, such as those needed for photoluminescence or FTIR spectroscopy We will also discuss initial purchase and operating costs, especially those relating to the availability of liquid helium, and whether a cryogen-free solution would better serve your cooling needs.

See you all next week at SPIE, the international society for optics and photonics exhibit in San Diego demonstrating products optimized for optical material and device research. On display in 📍Booth 409 will be: 🔹TTPX cryogenic probe station for performing temperature-dependent, on-wafer material or device measurements under vacuum 🔹M81-SSM synchronous source measure system for highly synchronized DC, 100 kHz AC, and mixed DC + AC sourcing and measuring 🔹ST-500 Environment by Janis optical cryostat. The TTPX station is designed for electro-optical materials characterization. It supports optional backside optical illumination of a sample, which is ideal for examining photosensitive materials with topside metallization. We also offer a wide range of stations for photovoltaic material and semiconductor optoelectronic device R&D, including configurations available for electro-optical, DC, RF, and microwave measurements, temperatures as low as 1.6 K, integrated magnetic field, and cryogen-free operation. Also available: fiber optic probing and feedthroughs, and load-lock and suitcase transfer options for delicate, air-sensitive samples. The M81-SSM system, which can be used to provide an excitation source for measurements performed in a probe station as well as a cryostat, features remotely mountable modules capable of providing combined DC+AC voltage/current outputs with very low noise levels for highly sensitive device characterization. The multichannel lock-in measurement system can, for example, be set up to stimulate and measure small photocurrents in a photodiode device mounted in a cryostat. The modular architecture of the M81-SSM allows for signal and source amplifiers to be mounted directly on the cryostat, minimizing noise and unwanted effects from cabling and wiring to the sample. Similar setups can be used for other optical experiments, such as external quantum efficiency (EQE) measurements of solar cell and photodetector devices. 📢 Also at SPIE Optics + Photonics, Lake Shore representatives will be available to discuss the company’s: 🔹Full line of Environment by Janis cryostats, cryocoolers, and other lab cryogenic equipment, including recirculating gas cooler (RGC) options for cooling liquid helium cryostats without the need for liquid cryogens 🔹Hall effect measurement solutions, including the M91 FastHall™ controller for faster, more precise Hall analysis of solar cell, organic electronic, and transparent conducting oxide materials 🔹New MagRS magnetic research system with options to customize it for Hall effect, vibrating sample magnetometry, and ferromagnetic resonance (FMR) measurements 🔹Cryogenic sensors and instruments for stable, reliable low-temperature measurements #SPIE
