2019 Second International Workshop on Mobile Terahertz Systems (IWMTS)
The monolithic on-chip integration and design of a high current density InP-based Triple Barrier Resonant Tunneling Diode within a bow-tie antenna structure for detection application is presented. The asymmetrical current-voltage characteristics of t
Wire-less sub-harmonic injection locking of a free running oscillator is presented. The free running oscillator consists of an InP-based triple barrier resonant tunneling diode integrated in a slot antenna designed for oscillation at f 0 from 31 GHz

Common thermoelectric generators are based on the Seebeck effect, which describes the thermal diffusion of majority charge carriers within a temperature gradient in a solid. It is a unipolar transport phenomenon that gets suppressed if bipolar charge
