Excitonic electroreflectance spectrum of cuprous oxcide at room temperature
We have studied the blue-green and blue exciton series spectra of cuprous oxide (Cu2O) with electrolyte electroreflectanoe method at room temperature and performed experimental results to be the least-square fit to Aspnes theory. Comparing the fit results with the experimental results of reflection and absorption spectra at low and room temperature, we get that the electaorefleotanoe spectra of Cu2O include not only n=l exciton effect of blue-green and blue series but also n=2 exctton effect. The eleotrorefleotance spectra of CuaO with different smoothing are measured and tho obvious spectral feature different is observed.
