Temperature dependence of the LO modes and the reversibility of the heating process. Temperature dependence of the LO modes of the InGaAs/GaAs system (a). The error bars of ±1 cm−1 represent the spectral resolution. (b) The reversibility of the heating process is verified using the 514.5 nm line of an Ar+ laser with a power measured at the sample of 50 μW.
