Direct energy gap of Sb2Te3 synthesised by solid-state microwave plasma

The usefulness of microwave heating and microwave generation of plasma for solid-state synthesis of Sb2Te3 crystals is reported. Lengths of time and molar ratios of Sb:Te were varied to achieve pure products heated by a 900 W microwave-irradiated plasma. In the present research, the products were Sb...
