Electronic Devices based on semiconducting strontium titanate

We explored the feasibility of employing strontium titanate SrTiO3 as semiconducting material in field effect and ferroelectric field effect epitaxial devices. Oxygen reduced SrTiO3-\u3b4 exhibits low temperatures mobility values comparable with those commonly found for silicon. By Pulsed Laser Deposition, we realized patterned field effect devices, showing a resistance modulation up to 90%. These results could open new perspectives for crystalline oxides electronics
