Open AccessResonant plasmonic detection of terahertz radiation in field-effect transistors with the graphene channel and the black-As \(_x\) P \(_{1-x}\) gate layer
We propose the terahertz (THz) detectors based on field-effect transistors (FETs) with the graphene channel (GC) and the black-Arsenic (b-As) black-Phosphorus (b-P), or black-Arsenic-Phosphorus (b-As ...

Terahertz and infrared photodetectors based on multiple graphene layer and nanoribbon structures
We consider new concepts of terahertz and infrared photodetectors based on multiple graphene layer and multiple graphene nanoribbon structures and we evaluate their responsivity and detectivity. The performanc...

First-principle calculation of the recombination cross-section assisted by acoustic phonons at shallow impurities in semiconductors
An original Monte Carlo study of the equilibrium microscopic and macroscopic recombination cross-sections at shallow impurity centres is presented. Both cross-sections are investigated in lightly dopedp-Si as fun...
