X-ray induced persistent photoconductivity in Si-doped Al${}_{0.35}$Ga${}_{0.65}$As

Yeong-Ah Soh, G. Aeppli, Frank M. Zimmermann +2

We demonstrate that X-ray irradiation can be used to induce an insulator-metal transition in Si-doped Al${}_{0.35}$Ga${}_{0.65}$As, a semiconductor with {\it DX} centers. The excitatio…
