摘要：
We report on the experimental studies of photoluminescence from hot electrons in quantum wires which were fabricated on AlGaAs/GaAs hetero-structures by using electron beam lithography and wet chemical etching. Spatially resolved photoluminescence of the quantum wires was observed by using microscopic photoluminescence (mu-PL) measurement at 70 K. We estimated the electron temperature from the mu-PL spectra in quantum well and wire. As a result, the spatial fluctuation of the electron temperature in the quantum wire was shown.
