A low-noise cryogenic amplifier for the bandwidth from 100 kHz to 2 MHz with commercially available components is presented. The amplifier is mounted on the cold finger of our home-made liquid helium dipstick. The inp...
The zincblende ternary alloys Tl_xGa_(1-x) As(0 〈 x 〈 1) are studied by numerical analysis based on the plane wave pseudopotential method within the density functional theory and the local density approximation....
