Synthesis and Analysis of Heterostructural Semiconductor Alloy Sn1-xCaxCh (Ch=S, Se) and Nitrides Zn1-xWxN and Zn1-x(W1-yMoy)xN

Creator:

Matthews, Bethany E.

Abstract:

This work explores the synthesis and characterization of the metastable alloys Sn1-xCaxCh (Ch= S, Se) and nitride compounds Zn-W-Mo-N, which have recently been predicted by theorists. Single phase thin films of Sn1-xCaxS are prepared by pulsed laser deposition and radio-frequency magnetron sputtering and of Sn1-xCaxSe are prepared by pulsed laser...

Terahertz Induced Non-linear Electron Dynamics in Nanoantenna Coated Semiconductors at the Sub-picosecond Timescale

Creator:

Stickel, Andrew

Abstract:

This dissertation is an exploration of the material response to Terahertz (THz) radiation. Specifically we will explore the ultrafast electron dynamics in the nonperturbative regime in semiconductors that have been patterned with nanoantenna arrays using broadband, high intensity, THz radiation. Three main semiconductor materials will be studied in this work....

Terahertz imaging and spectroscopy of carbon-based and semiconductor nanostructures

Creator:

Tomaino, Joseph L.

Abstract:

This thesis will cover work that I have completed relating to the field of terahertz (THz) science. My work has consisted of generating tunable, narrowband THz pulses in a table-top optical setup and using both narrow- and broadband THz pulses to study various material systems. Broadband THz pulses were used...
