Development of phonon-polarization THz spectroscopy, and the investigation of relaxor ferroelectrics
… development of pulsed THz radiation sources and time-domain detection methods. Four factors motivate the use of phonon-polaritons generated in an ionic crystal (typically LiNbO3 or LiTaO3) via impulsive stimulated Raman scattering as a THz source for spectroscopy: (1) the versatility of …

Picosecond Spin Seebeck Effect in Magnetic Insulators
… as heat source. This study uses Terahertz (THz) time-domain emission spectroscopy where a femtosecond laser induces a thermal gradient that lasts for only a few picoseconds and the SSE signal manifests as broadband THz electric field radiation. The ultra-fast laser excitation and detection …

The Integration and Applications of Organic Thin Film Transistors and Ferroelectric Polymers
… while also increasing the charge retention time. A bipolar detector is created by using a UV-Ozone treatment to shift the threshold voltage and increase the current of the transistor under both compressive and tensile strain. An array of strain sensors which maps the strain field on a PVDF …
