Wet-etched phononic crystal waveguiding on GaAs
(IOP Publishing, 2018-01-10)
A wet-etched phononic crystal waveguide in GaAs with approximately two micron deep inclusions is studied both numerically and experimentally for controlled surface acoustic wave propagation. Numerically, the phononic crystal ...
Phononic Crystal Surface Structures on Gallium Arsenide
A series of computational studies of surface phononic crystals on cubic gallium arsenide are explored to elucidate the behaviour of surface acoustic waves in such systems. The enhanced understanding of surface acoustic ...
