Abstract
In this research, a semi-classical drift-diffusion 3D modeling have been developed to predict the rectification behavior and noise spectra of both the ballistic rectifiers considered in this research. Furthermore, the developed model predicts that minimum low frequency noise for both the devices which depends upon carrier concentration inside device active region rather than mobility, enables potential applications as THz detectors for imaging.
Further, it has been demonstrated that symmetric geometry of both type of ballistic rectifiers, i.e. three terminals and four terminals, can be utilized as a thermoelectric rectifier for wide variety of applications to produce rectified output voltage converting thermal energy radiated from the electronic devices/ICs. Prototypes of ballistic rectifiers with and without antidot have been developed demonstrating rectification of microwave/RF signals.
The development of this novel technology of Ballistic Rectifier can be used for various applications including future generation communications, signal detection, medical and security imaging.
