Electron-photon interaction in resonant tunneling diodes

– We develop a model to describe the transmission coefficient and tunneling current in the presence of electron-photon coupling in a resonant diode. Our model takes into account multiphoton processes as well as the transitions between electronic states with different wave numbers. This is crucial to explain the experimental features observed in the tunneling current through a double barrier whi...

Ferromagnetic Resonant Tunneling Diodes: Physics and Applications

Dedication To my family. v Acknowledgements I would like to acknowledge, foremost, my advisor Prof. Sanjay Banerjee. I should thank him for providing me the opportunity to pursue graduate study, his constant support for the last six years – both intellectual and material, and the flexibility he afforded to me to define and follow my interests. Second, I would like to acknowledge my co-advisor P...

Photo-Detectors Integrated with Resonant Tunneling Diodes

We report on photo-detectors consisting of an optical waveguide that incorporates a resonant tunneling diode (RTD). Operating at wavelengths around 1.55 μm in the optical communications C band we achieve maximum sensitivities of around 0.29 A/W which is dependent on the bias voltage. This is due to the nature of RTD nonlinear current-voltage characteristic that has a negative differential resis...
