Graduate Theses and Dissertations
Due to the advanced focusing ability, characterization methods based on the electron-beam excitation have been broadly applied to investigate nanomaterials. Structural or compositional information is commonly acquired using electron microscopes. Moreover, taking advantage of the super spatial resolution of the focused electron beam, optical properties of nanomaterials can be also obtained. Herein, general concepts and processes of the interaction between electrons and materials are studied. Two specific optical nanomaterials, including plasmonic nanostructures and semiconductor quantum layers, are investigated by the cathodoluminescence (CL) measurement.
Surface plasmonic resonance can be generated when high-energy electrons strike the interface between the dielectric medium and …
Progress Towards Terahertz Acoustic Phonon Generation In Doping Superlattices, Thomas E. Wilson
Progress Towards Terahertz Acoustic Phonon Generation In Doping Superlattices, Thomas E. Wilson
Thomas E. Wilson
Progress is described in experiments to generate coherent terahertz acoustic phonons in silicon doping superlattices by the resonant absorption of nanosecond-pulsed far-infrared laser radiation. Future experiments are proposed that would use the superlattice as a transducer in a terahertz cryogenic acoustic reflection microscope with sub-nanometer resolution.
