Piezoelectric coupling, phonons, and tunneling into a quantum Hall edge [PDF]
, 2005 We show that the piezoelectric coupling to three-dimensional phonons in GaAs renormalizes the current-voltage exponent for tunneling of electrons into an incompressible quantum Hall edge.

Importance of second-order piezoelectric effects in zincblende semiconductors
, 2006 We show that the piezoelectric effect that describes the emergence of an electric field in response to a crystal deformation in III-V semiconductors such as GaAs and InAs has strong contributions from second-order effects that have been neglected so far.
