Direct measurement of interfacial Dzyaloshinskii-Moriya interaction at the MoS/NiFe interface
Akash Kumar, Avinash Kumar Chaurasiya, Niru Chowdhury +8
We report on a direct measurement of sizable interfacial Dzyaloshinskii-Moriya interaction (iDMI) at the interface of two-dimensional transition metal dichalcogenide (2D-TMD), MoS$…
Binary Multifunctional Ultrabroadband Self-Powered g-C3N4 /Si Heterojunction High-Speed Photodetector
Nisha Prakash, Gaurav Kumar, Manjri Singh +5
Compact optical detectors with fast binary photoswitching over a broad range of wavelength are essential as an interconnect for any light-based parallel, real-time computing. Despi…
Ultrasensitive Self-powered large area planar GaN UV-photodetector using reduced graphene oxide electrodes
Nisha Prakash, Manjri Singh, Gaurav Kumar +5
A simplistic design of a self-powered UV-photodetector device based on hybrid r-GO/GaN is demonstrated. Under zero bias, the fabricated hybrid photodetector shows a photosensivity…
Continuous-wave coherent imaging with terahertz quantum cascade lasers using electro-optic harmonic sampling
Marco Ravaro, Vishal Jagtap, Giorgio Santarelli +5
We demonstrate a coherent imaging system based on a terahertz (THz) frequency quantum cascade laser (QCL) phase-locked to a near-infrared fs-laser comb. The phase locking enables c…
Terahertz quantum cascade lasers with thin resonant-phonon depopulation active regions and surface-plasmon waveguides
M. Salih, P. Dean, A. Valavanis +5
We report three-well, resonant-phonon depopulation terahertz quantum cascade lasers with semi-insulating surface-plasmon waveguides and reduced active region (AR) thicknesses. Devi…
Radiative Recombination Spectra of Heavily p-Type delta-Doped Gaas/Alas MQWs
J. Kundrotas, A. Cerskus, G. Valusis +4
We present a study of the photoluminescence (PL) properties of heavily Be delta-doped GaAs/AlAs multiple quantum wells measured at room and liquid nitrogen temperatures. Possible m…
