IEEE Journal of the Electron Devices Society, 2018 Ambient instability has been proven challenging in black phosphorus field-effect transistors (BP FETs) and a capping layer is thus needed for their practical applications. In this paper, we have examined the effects of Al2O3 capping and O2 post-annealing

Bias‐Tunable Two‐Terminal Organic Photodetector for Intelligent Imaging
Advanced Science, EarlyView.A vertically stacked two‐terminal photodetector with a symmetric donor–acceptor–donor trilayer active exhibits reconfigurable photoresponse with bias‐tunable magnitude and polarity, together with sub‐millisecond response speed and a wide tunable output window.

Advanced Science, EarlyView.The electrolyte engineering of introducing tetrakis(4‐N, N‐dimethylaminophenyl)porphyrin (TDMAP) is designed to modulate Li+ solvation structure and solid electrolyte interphase, where the interaction with PF₆− anions is altered (Li+–NMe2–PF₆−). Consequently, the cells with optimal additive concentration achieve high Coulombic efficiency (∼99%), and ...

Bandgap modulated phosphorene based gate drain underlap double-gate TFET
AIP Advances, 2018 In this work, a novel bandgap modulated gate drain underlap (BM-GDU) structure of tunnel-FET exhibiting suppressed ambipolar characteristics and steep SS is proposed by applying layer dependent bandgap and electron affinity property of 2-D material ...

Advanced Science, EarlyView.We synthesized a high‐performance balanced ambipolar OECT polymer, P(gTDPPSe), via selenophene π‐bridge engineering. The selenophene π‐bridge enhances backbone planarity and optimizes the energy levels for doping, enabling high and balanced p/n‐type transconductance‐a key factor for high‐gain complementary inverters.

Improvement in the Performance of Tunneling Carbon Nanotube Field Effects Transistor in Presence of Underlap [PDF]
مجله مدل سازی در مهندسی, 2019 Underlap between gate and drain/source area is one of the important items non-ideal effects in the device manufacturing process in the nanometer scale. In this paper, for the first time, the effect of underlap between the gate and drain/source area for ...

Advanced Science, EarlyView.Two‐dimensional CuInP2S6 nanosheets are incorporated into a P(VDF‐TrFE) matrix to induce polarization‐cooperative ferroelectric coupling. The resulting P(VDF‐TrFE)/CuInP2S6 hybrid film exhibits reinforced ferroelectric ordering and reduced coercive electric fields compared with pristine P(VDF‐TrFE).
