Electron-hole Drops
Part of the Lecture Notes in Physics book series (LNP, volume 57)


Luminescence and electrical measurements have been performed in pure and As-doped germanium at 1.6 – 4.2 K under intense optical excitation. Under extremely high excitation of pure germanium, it is found that the electron-hole liquid phase is uniformly generated in the whole volume of the sample. From the observation of the giant fluctuating current, the electron-hole drops turn out to be negatively charged as a whole. Even in heavily doped germanium, it is found that the EHD is formed stably in an atomosphere of metallic electrons released from donor impurities.
