Abstract Ultrasensitive photodetectors with polarization angle recognition have broad applications in both civilian and military domains. The emerging 2D materials in‐plane anisotropy offer promising platforms for realizing these applications, owing to their intriguing properties. However, the lack of an effective photoconductivity gain mechanism low photocurrent anisotropic ratio made it chall...

Graphene–organic heterojunction phototransistors have great potential to achieve sensitive photoresponse owing the excellent absorption of organic layers and fast charge transport in graphene. However, most graphene-based is limited within visible light region with narrow bandwidth poor sensitivity near-infrared (NIR) region. Herein, a graphene–organic NIR phototransistor fabricated by integrat...

In this research, a urea level sensor based on plastic optical fiber was made using the macro bending method and two kinds of configurations. The is with gamma band configuration variety cladding, no imperfection immersed in urine sample which has different urea. This aimed at determining optimal as sensor. object measured concentrations ranging from 336.1 mg/dL to 1384.3 mg/dL, same volume for...

The 2D semimetallic electrodes have been employed to show outstanding contact properties with semiconducting transition‐metal dichalcogenides (TMDCs) channel, leading large enhancement of transistor and phototransistor performance. Herein, an innovative concept is established for a unique electrode‐2D TMDC channel (2D–2D) device configuration where the electronic structures are systematically m...

Abstract Various studies on multi-valued-logic (MVL) computing, which utilizes more than two logic states, have recently been resumed owing to the demand for greater power saving in current technologies. In particular, unlike old-fashioned researches, extensive efforts focused implementing single devices with multiple threshold voltages via a negative-differential change phenomenon. this work, ...
