Abstract

Thermal evaporation made trigonal-phase Al2O3 nanowires are coated with amorphous TiO2 using atomic layer deposition and subsequent annealing results in crystallization of the coating and creation of abundant oxygen deficient states at the interface. Interfacial states behave as electron acceptors upon charging and capacitance density has been measured to be three orders of magnitude greater than existing data.
