Laser-Combined Scanning Tunneling Microscopy on the Carrier Dynamics in Low-Temperature-Grown GaAs/AlGaAs/GaAs
Figure 6
(a) Line profiles of at different with the tip scanned across the AlGaAs/LT-GaAs interface. Each profile is offset by 0.5 pA steps for clarity. (b) Time evolution of in-plane band diagram near the interface: (i) before excitation and (ii) immediately after excitation. , .
