16. Adventures of III-V Semiconductor Surfaces
Abstract : Tailoring the surface composition and morphology of materials to enable new electronic devices is important for a wide range of applications such as quantum computing or spintronics. A fundamental understanding of the changes induced in the surface during different process steps can help to establish new synthesis routes as well as devices. READ MORE

18. Selective Epitaxy of Indium Phosphide and Heteroepitaxy of Indium Phosphide on Silicon for Monolithic Integration
Abstract : A densely and monolithically integrated photonic chip on indium phosphide is greatly in need for data transmission but the present day’s level of integration in InP is very low. Silicon enjoys a unique position among all the semiconductors in its level of integration. READ MORE

19. Metamorphic Heterostructures and Lasers on GaAs
Abstract : The objective of this thesis is to demonstrate the metamorphic growth of heterostructure lasers on GaAs substrates. Many heterostructure devices have their performance limited by the need to grow on lattice-matched substrates. READ MORE

20. Photonic terahertz-wave generation, radiation and quasioptical integration
Abstract : This thesis deals with the uni-travelling-carrier photodiode (UTC-PD) based photonic generation of terahertz waves, antenna designs for the terahertz radiation and a novelcatadioptric lens for quasioptical integration.The ongoing and accomplished research work on the UTC-PD, its limitations and optimisation scopes for attaining higher bandwidth and higher output power have been discussed.
