Surface Acoustic Waves in Thin Films Nanometrology [PDF]

, 2015
Thin films nanometrology is an emerging field in nanoscience as the synthesis, processing and applications of nanostructured thin films require an in-depth knowledge of their elastic constants. The elastic energy of a surface acoustic wave propagating in

Investigation of bulk acoustic microwaves excited by an interdigital transducer

Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2015
Excitation of bulk and surface acoustic waves with the interdigital transducer (IDT), which is deposited on the surface of a piezoelectric crystal, is widely used in the development of devices in acoustoelectronics and in the design of the microwave ...

Quantized charge pumping through a quantum dot by surface acoustic waves

, 2003
We present a realization of quantized charge pumping. A lateral quantum dot is defined by metallic split gates in a GaAs/AlGaAs heterostructure. A surface acoustic wave whose wavelength is twice the dot length is used to pump single electrons through the
