Thin films of TiO2 were prepared from gas mixtures of TiCl4 and O2 using rf glow discharge. TiO2 films were grown on glass, Si, Ti and MgO substrates at temperatures as low as 200°C by applying an rf power of 10W, although no film was deposited with

By the power spectrum analysis of the quantum oscillations of the sound velocity in antimony, the geometrical factors G of the energy surfaces were studied. For holes it was found that G is ellipsoidal for the light mass directions. The coupling cons

The band edge structures of p -Pb 1- x Ge x Te are studied by measuring the quantum oscillations of the sound velocity and the RF-surface impedance for five different values of x at 1.4 K. The angular dependences of the periods become more complicate
