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...

X-rays, but they are very large and expensive, which limits them to user- facilities. 1.3.2
High-Field Terahertz Spectroscopy of Nanoscale Materials

Creator:

Mousavian, Ali

Abstract:

This dissertation covers my work relating to the application of strong terahertz (THz) radiation to study the nonlinear properties of nano-scale material. It presents experimental and numerical studies on the optical and electronic properties of various material system including single-layer graphene, multi-walled carbon nanotubes (MWCNTs), nanoantenna-patterned gallium arsenide (GaAs) and...
