Giant piezoresistive effect by optoelectronic coupling in a heterojunction [PDF]

, 2019
Enhancing the piezoresistive effect is crucial for improving the sensitivity of mechanical sensors. Herein, we report that the piezoresistive effect in a semiconductor heterojunction can be enormously enhanced via optoelectronic coupling.

Bulk Heterojunction versus Diffused Bilayer: The Role of Device Geometry in Solution p-Doped Polymer-Based Solar Cells [PDF]

, 2012
We exploit the effect of molecular p-type doping of P3HT in diffused bilayer (DB) polymer solar cells. In this alternative device geometry, the p-doping is accomplished in solution by blending the F4-TCNQ with P3HT.

Enhanced photoluminescence of a CsPbBr3/Al2O3 film heterojunction enabled by coupling of gold nanoparticles

Materials Research Express, 2020
We studied an enhanced photoluminescence (PL) effect of CsPbBr _3 /Al _2 O _3 heterojunction by using gold nanoparticls (NPs). The CsPbBr _3 /Al _2 O _3 heterojunction and CsPbBr _3 /Au/Al _2 O _3 heterojunction were respectively prepared on porous Al _2

Tunable electronic structure in twisted WTe2/WSe2 heterojunction bilayer

AIP Advances, 2022
Electronic structures of non-twisted and twisted WTe2/WSe2 heterojunction bilayers were investigated using first-principles calculations. Our results show that, for the twisted WTe2/WSe2 heterojunction bilayer, the bandgaps are all direct bandgaps, and ...
