AC-Hopping Conductance of Self-Organized Ge/Si Quantum Dot Arrays

Irina L. Drichko, Andrey M. Diakonov, Veniamin I. Kozub +4

Dense ($n=4\times 10^{11}$ cm${}^{-2}$) arrays of Ge quantum dots in Si host were studied using attenuation of surface acoustic waves (SAWs) propagating along the surface of a piezo…
