Titanium disilicide is formed by thermal annealing of amorphous Si/Ti multilayers, deposited on monocrystalline silicon by alternate electron‐gun evaporation of Si and Ti. The bilayer periodicity was equal to 4. The bilayer Si/Ti thickness ratio wa

The point-to-point resolution of Auger electron spectroscopy is compared to that of x-ray microanalysis of thin unsupported films and of thin films on a bulk material. Monte-Carlo calculations are used in this respect. The incident beam is a Gaussian

We present time-resolved International Ultraviolet Explorer observations of the low-mass X-ray binary AC211/4U2127+11 in the globular cluster M15 (NGC 7078). The spectra show He II 1640-A emission, the flux of which is modulated on the 8.5-hr orbital

The current‐voltage characteristics of p‐channel MOSFETs (metal‐oxide‐semiconductor field‐effect transistors) in the temperature range 4.2‐50 K have been investigated in detail. A peak is observed at the beginning of the drain‐current
