Scattering analysis of 2DEG mobility in undoped and doped AlGaN/AlN/GaN heterostructures with an in situ Si3N4 passivation layer
(Pergamon-Elsevier Science LTD, 2016)The scattering mechanisms limiting mobility for low-dimensional charge carriers in a two-dimensional electron gas (2DEG) in undoped and doped AlGaN/AlN/GaN heterostructures with and without Si3N4 passivation are investigated. ... -
Scattering from a PT symmetric standing wave
(Elsevier, 2012)We study the Kapitza-Dirac diffraction of a free beam particle in the presence of a PT symmetric standing wave. We discuss that the momentum and total probability are not conserved in the non-Hermitian scattering process. ... -
Scattering of sound waves by an infinite grating composed of rigid plates
(Elsevier Science BV, 2007)A plane sound wave is incident at an angle theta upon an infinite array of rigid plates, equally spaced and lying along the y-axis, where (x, y) are two-dimensional Cartesian coordinates. The boundary value problem is ... -
