Dependence of Photocurrent Enhancements in Hybrid Quantum Dot-MoS2 Devices on Quantum Dot Emission Wavelength
(2019)The spectral dependence of nonradiative energy transfer (NRET) from three spectrally different quantum dot (QD) ensembles to monolayer MoS2 is reported. The QDs with peak emission wavelengths of 450, 530, and 630 nm induce ... -
Description of polarisation dependence of two-photon absorption in silicon avalanche photodiodes
(2010)A simple formula is obtained that very accurately describes the level of two-photon absorption (TPA) generated by elliptically polarised light in silicon avalanche photodiodes (Si-APDs). The dichroism parameter necessary ... -
Evolution of resistive switching over bias duration of single Ag2S nanowires
(2010)We report experimental results of ultralow frequency photocurrent oscillation in individual ZnO nanowires. Consecutive photocurrent and photoluminescence measurements corroborate the process of capture and release of ... -
Nonradiative Energy Transfer and Photocurrent Enhancements in Hybrid Quantum Dot-MoS<inf>2</inf> Devices
(2018)The energy transfer mechanism leading to highly efficient nonradiative energy transfer (NRET) from quantum dots (QDs) to monolayer MoS 2 devices has been investigated via a spectral dependence study. The spectral dependence ...
