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...

Nonlinear Terahertz Spectroscopy and imaging of Carbon Nanomaterials

Creator:

Lee, Byounghwak

Abstract:

This dissertation presents nonlinear terahertz (THz) properties of carbon nanomaterials investigated by time-resolved high-field THz spectroscopy. In order to determine THz characteristics of nanomaterials, we performed THz power spectrum measurement, THz raster imaging, THz time-domain spectroscopy (THz-TDS) and time-resolved pump-probe experiment on two different types of single layer graphene and...

Terahertz Imaging and Nonlinear Spectroscopy of Semiconductors using Plasmonic Devices

Creator:

Thompson, Zachary James

Abstract:

In this dissertation, a series of studies in the field of terahertz (THz) science are presented, specifically using nonlinear THz spectroscopy. We exploit huge field enhancement and subwavelength confinement in plasmonic structures. There are three distinct projects which will be discussed: nonlinear THz spectroscopy using plasmonic induced transparency (PIT), THz-triggered...
