In this work, p-n junctions are made from directly depositing optimal doped La1.85Sr0.15CuO4 (LSCO) films on n-type Nb-doped SrTiO3 substrates. Film thickness controlled rectifying behaviors are strikingly displayed...
The effects of working pressure on properties of Al2O3 thin films are investigated. Transmittance of the Al2O3 thin film is measured by a Lambda 900 spectrometer. Laser-induced damage threshold (LIDT) is measured by...
We have studied the radiation of a double-walled carbon nanotube (DWNT) filament with a length of 4.5 mm and a diameter of 10μm by applying an electric current through the filament. The DWNT filament starts emittin...
