Abstract:
High efficiency GaAs-based lasers must have low resistance. However, resistance diverges as temperature reduces, for symmetric and asymmetric vertical structures, at diverse wavelengths, contrary to expectation from bulk mobilities. Resistance increases with quantum well depth and is reduced for p-doped quantum wells.
