Ultrahigh resolution surface phononics
… is crucial in many research field related to phononics. Phonon linewidths are typically influenced by three different mechanisms, which are phonon-phonon interaction, defect-phonon interaction, and electron-phonon interaction, which are all discussed in this thesis. Chapter 2 provides a …

Control of Nanoscale Thermal Transport for Thermoelectric Energy Conversion and Thermal Rectification
… These materials have potential application in phononics, i.e., for performing logic calculations with phonons. Rectification obtained with existing material systems is either too small or too difficult to implement. In this thesis, a more useful scheme is presented that provides higher …

Hybrid direct write lithographic strategies for complex hierarchical structures
… forward on a lab scale for applications such as phononics, photonics, and plasmonics can be realized in the industrial scale. This thesis, in approaching this challenge, utilizes combinations of patterning techniques, leveraging the ability for "large" scale alternative lithographic techniques, …

Hypersound interaction studied by time-resolved inelastic light and x-ray scattering
… phonon wave packets which we call "nonlinear phononics" in analogy with the nonlinear optics, which summarizes a kaleidoscope of surprising optical phenomena showing up at very high electric fields. Such phenomena are for instance Second Harmonic Generation, four-wave-mixing or solitons. But …

The taiji and infinity-loop microresonators: examples of non-hermitian photonic systems
This thesis theoretically and experimentally studies the characteristics of integrated microresonators (MRs) built by passive (no gain) and non-magnetic materials and characterized by both Hermitian and non-Hermitian Hamiltonians. In particular, I have studied three different microresonators: a …
