Recent Advances in Xenes Based FET for Biosensing Applications

open access: yesAdvanced Science, EarlyView.
Xenes (monoelemental 2D materials like graphene, phosphorene, tellurene) enable ultrasensitive FET (Field‐Effect Transistor) biosensors due to their tunable bandgap, high carrier mobility, and large surface area. Advances in synthesis (CVD, MBE) and functionalization allow detection of DNA/RNA (via CRISPR‐Cas systems), proteins, small molecules, and ...

Real‐Time Self‐Optimization of Quantum Dot Laser Emissions During Machine Learning‐Assisted Epitaxy

open access: yesAdvanced Science, EarlyView.
This work presents a machine learning‐driven approach integrated with in situ high‐energy electron diffraction (RHEED) monitoring to automate the optimization of quantum dot (QD) growth for lasers. A 3.2‐fold increase in photoluminescence intensity is achieved alongside a narrow spectral linewidth.

Solid State Defect Emitters With no Electrical Activity

open access: yesAdvanced Science, EarlyView.
Point defects may introduce in‐gap states that alter electrical properties and lower the optical excitation threshold. It is thus widely assumed that solid‐state defect emitters alter the host conductivity. This study demonstrates, on a particular defect in 4H silicon carbide, that a yet unrecognized class of point defects exists that are optically ...

Self‐Powered UV Dual‐Band Photodetector Based on Cs3BiCl6/GaN Heterojunction for Logical Operation and Encrypted Photo‐Communication

open access: yesAdvanced Science, EarlyView.
Utilizing the special dual‐band absorption characteristics of Cs3BiCl6 and its strong surface‐charge recombination behavior, a self‐powered UV dual‐band photodetector based on Cs3BiCl6/GaN heterojunction is developed. As a result, the photodetector exhibits excellent specific detectivity of 1.23 × 1012 Jones and ultrafast response speed of τr/τf = 28 ...

Intraoperative Fast Adaptive Focus Tracking Robotic OCT Enables Real‐Time Tumor Grading and Large‐Area Microvascular Imaging in Human Spinal Cord Surgery

open access: yesAdvanced Science, EarlyView.
The fast adaptive focus tracking robotic optical coherence tomography (FACT‐ROCT) offers real‐time, high‐resolution imaging of spinal cord tumors during surgery. By reducing motion artifacts with robotics and adaptive focal tracking, it accurately differentiates tumor grades using a novel attenuation coefficient marker and reveals critical ...
