Electron eigen-states in InGaAs/InAlAs multi-quantum wells using photocurrent spectroscopy


Photocurrent spectroscopy in lattice matched In<sub>0:53</sub>Ga<sub>0:47</sub>As/In<sub>0:52</sub>Al<sub>0:48</sub>As multi-quantum wells structures were measured at room temperatures. Step-like structures accentuated by the exciton peaks of interband transitions were observed on photocurrent spectra. The exciton peaks clearly appeared at lower quantum… (More)
