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…
