Researchers at Nanjing University of Posts and Telecommunications have made strides in developing ultraviolet (UV) photonic integrated circuits (PICs) on silicon substrates. The team integrated four diodes into a single level via a gallium nitride waveguide, opening up possibilities for UV microscopy, biosensing, and on-chip data communication. Despite current limitations in data transmission rates, the new PIC chip holds potential for audio transmission and sensor applications. https://lnkd.in/dkkFAB_5 #Photonics #IEEE

Graphene nanoribbon breakthrough: GNR to GNR distance matters! 🔬 In my latest research, I've discovered something fascinating about GNRFET structures. The spacing between graphene nanoribbons \(GNRs\) is critical. Here's why it's a game-changer: 1. Enhanced gate control 2. Reduced leakage current 3. Improved on/off ratio This could lead to faster, more efficient nanoelectronics. What's your take on the future of GNRFETs in next-gen devices? #Nanotechnology #Graphene #ElectricalEngineering

I'm very excited to announce the publication of our latest research! Our paper, titled "First-Principle Investigation of zb-TiGe: A Promising Narrow Band-gap Semiconductor". This study provides a detailed description of a new narrow band-gap semiconductor's electronic band structure, carrier effective mass, charge density distribution, and linear optical properties. The linear optical properties of the TiGe are found to be suitable for photosensitive devices in the infrared region. In addition, TiGe may find application in deep-UV and far-UV regions because of the surface plasmon resonance at 6.4 eV. Check out the full article here: 10.1002/pssb.202400475

New paper alert: Our latest publication in Physical Review Letters (PRL) reports measurements on single-layer WSe2, a representative p-type 2D semiconductor. The devices exhibit low contact resistance and remarkably high mobility (25,000 cm^2/V.s), even at elevated temperatures. Notably, we observed a unique dependence of mobility on carrier density. These samples were exfoliated from crystals grown using the flux method by our collaborators, and we are currently producing comparable high-quality samples at UCI. https://lnkd.in/gd8Dt7g7

Researchers at the National University of Singapore have demonstrated a non-volatile photonic-electronic memory using a 3D monolithic integrated ferroelectric-silicon ring resonator, as published in Nature Communications. This memory can be accessed both electrically and optically, bridging electronic and photonic circuits while maintaining compatibility with large-scale CMOS integration. The device shows promising performance with a high optical extinction ratio and multi-level storage capability, potentially enabling advances in photonic interconnects, high-speed data communication, and neuromorphic computing.

In this study, researchers demonstrated a high-intensity spatial-mode steerable frequency up-converter in both temperature and wavelength manipulating methods. Stable TM 01, TM 10, and TM 00 modes at the sum–frequency generation (SFG) wavelength could be prepared automatically within a few-mode periodically poled LN waveguide without prefabricating the spatial modes of the incident signal and pump lights by adjusting the incident combined lights or using a spatial light modulator. This result is appealing for on-chip integration with the microlasers such as distributed feedback laser (DFB) or semiconductor optical amplifier.
