Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

Advanced Science, EarlyView.
A MoTe2/WSe2/Cl–SnSe2 unipolar barrier photodetector is demonstrated, in which the WSe2 layer effectively blocks majority‐carrier injection, yielding suppressed dark current and enhanced near‐infrared (NIR) sensing. The device achieves high detectivity, a wide linear dynamic range, and fast response under 1310 nm illumination, enabling high‐fidelity 3D

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

Advanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Effect of central obscuration on the LDR point spread function [PDF]

, 1988
It is well known that Gaussian apodization of an aperture reduces the sidelobe levels of its point spread function (PSF). In the limit where the standard deviation of the Gaussian function is much smaller than the diameter of the aperture, the sidelobes ...

Green Ambiguity Shapes Sustainable Investing

Business Strategy and the Environment, EarlyView.
ABSTRACT Green Exchange‐Traded Funds (ETFs) have experienced strong growth in recent years, reflecting increasing investor attention toward sustainability. However, these funds rely on a wide range of environmental metrics that are often weakly aligned, raising concerns about the meaning of greenness in sustainable investing.
