Soft X-ray standing waves with wavelength equal to twice the distance between successive carbon layers are observed by measuring the synchrotron-radiation-pumped soft X-ray absorption spectrum of SiCl 4 -graphite intercalation compounds. It is shown

Backscattering yields of 1.5 MeV−He + ions and low temperature photoluminescence (PL) spectra were measured in GaP crystals implanted with 200 keV−N + ions as functions of ion-dose, temperature during implantation and annealing temperature after

From magnetoplasma experiments at 50 GHz for n -Pb 1- x Sn x Te (0≤ x < 0.3), a static dielectric constant e s is determined as a function of x . For x =0, 0.063, 0.091, 0.152 and 0.293, e s is found to be 1410, 1770, 2840, 4610 and 10800 at 1.6 K,

Red luminescence in CdS has been studied in as‐grown and ion‐implanted crystals. An IR band consisting of two emission bands, IR1 and IR2, is produced by ion implantation. The higher‐energy band, IR1, has the same origin as the R band observed

Low temperature growth of silicon epitaxial layers has been performed by two methods: by molecular beam epitaxy and by solid-phase crystallization of amorphous films deposited onto crystalline substrates under ultra-high vacuum.

Two types of non-crystalline states (“disordered” and “amorphous”) of GaP were produced by using ion implantation and post annealing. A structural-phase-transition-like annealing behaviour from the “disordered” state to the “amorphous

The electrical conductivity of disordered layers in GaAs produced by ion implantation has been studied as a function of ion species, dose level, energy of implanted ions, and anneal temperature. The resistivity of the implanted layer, ρ, at room tem
