Dynamical formation of hot-carrier intergroup noise under sub-terahertz cyclostationary conditions

We show the existence of an upconversion of low-frequency intergroup noise by means of Monte Carlo simulations in bulk materials and semiconductor structures operating under periodic large-signal regime. The intergroup noise is associated with stochastic transitions in momentum space of carriers bet...

Summary:We show the existence of an upconversion of low-frequency intergroup noise by means of Monte Carlo simulations in bulk materials and semiconductor structures operating under periodic large-signal regime. The intergroup noise is associated with stochastic transitions in momentum space of carriers between regions characterized by different dynamics originated by the presence of hot-carrier conditions.
