Capacitively Coupled GaAs p-i-n/Substrate Photodetector with Ohmic Contacts on Lightly Doped n-GaAs for Hard X-Ray Imaging
V. G. Harutyunyan, S. D. Zilio, M. Colja +5
In this work, we present a capacitively coupled GaAs p +-i-n/substrate photodetector (CC-GaAs PIN/S PD), which also represents a preliminary step toward 3D detection (x, y, time) o…

Enhanced sensitivity of sub-THz thermomechanical bolometers exploiting vibrational nonlinearity
L. Alborghetti, B. Bertoni, L. Vicarelli +10
A common approach to detecting weak signals or minute quantities involves leveraging the localized spectral features of resonant modes, whose sharper lines (i.e. high Q-factors) en…
