A study of electron and phonon dynamics by broadband two-dimensional THz time-domain spectroscopy
Fu, Zhengping (Rensselaer Polytechnic Institute, Troy, NY, 2016-05)In this thesis, the coherent phonons excited by THz pulses are experimentally demonstrated for the first time in both GaAs and InSb. The resonant excitation using THz pulses enables the coherent control of the lattice ... -
Controlling electrical and thermal transport across metal-thermoelectric interfaces through chemical modification with a nanomolecular layer
Cardinal, Thomas (Rensselaer Polytechnic Institute, Troy, NY, 2016-12)Achieving high-efficiency thermoelectric devices for novel energy conversion applications such as on-chip cooling and refrigeration or waste-heat harvesting requires metal-thermoelectric interfaces with tailored electrical ... -
Design of silicon based terahertz transceiver
Wu, Kefei (Rensselaer Polytechnic Institute, Troy, NY, 2017-12)Moving from circuit blocks to sub systems with an outphasing transmitter architecture proposed to take advantage of the high output power from the frequency doubler. Through the outphasing mechanism, the PA frequency doubler ... -
Design, fabrication and optimization of silicon electro-optic modulators for digital and analog applications
Wu, Pengfei (Rensselaer Polytechnic Institute, Troy, NY, 2014-12)Two new device structures are explored theoretically. The tunneling modulator structure uses tunneling layers to cascade PiNs in a silicon rib waveguide. Compared with conventional PiN modulators, the proposed tunneling ... -
