Er. Brown et al., EFFECT OF LATTICE-MISMATCHED GROWTH ON INAS ALSB RESONANT-TUNNELING DIODES/, I.E.E.E. transactions on electron devices, 41(6), 1994, pp. 879-882
Nominally identical InAs/AlSb resonant-tunneling diodes are fabricated
on InAs and GaAs substrates to ascertain the effect of dislocations o
n the resonant-tunneling process. Although the diode on the GaAs subst
rate had a much higher dislocation density, as evidenced by x-ray diff
raction measurements, it displayed only a small decrease in peak-to-va
lley current ratio.
