Thickness-Induced Metal-Insulator Transition in Sb-doped SnO(2) Ultrathin Films: The Role of Quantum Confinement
A thickness induced metal-insulator transition (MIT) was firstly observed in Sb-doped SnO(2) (SnO(2):Sb) epitaxial ultrathin films deposited on [Image: see text] sapphire substrates by pulsed laser deposition. Both electrical and spectroscopic studies provide clear evidence of a critical thickness f...
