Abstract: | Surface and bulk properties of indium phosphate single crystals with initial and previously irradiated by 25 MeV electrons
structures were irradiated with 86Kr (253 MeV) and 197Au (200 MeV) up to various fluences. The modern methods of condensed matter studies were used for research of InP property
changes before and after irradiation as scanning (SEM) and high resolution transmission electronic microscopy (HTEM), Rutherford
backscattering spectroscopy (RBS/C) and atomic force microscopy (AFM). The comparison of obtained results with the results
of other authors is carried out. The surface structure change of InP single crystal irradiated by high-energy 86Kr ions and
electrons is studied. It is shown the changes of the InP surface have complicated character and caused by inelastic sputtering
processes. It is observed the twice irradiated layer swells with the cracks creation on the surface. The swelling with cracks
and strong sputtering of twice irradiated by electrons and ions with high energy layers of the InP and GaAs surfaces are explained
using the model based on the influence of ionizing energy loss of swift 86Kr ions. The small crystalline objects are detected on the InP surface irradiated with 86Kr ions which may be nano- and micro-crystals of InP. All obtained effects are discussed in frame of models based on ionizing
energy loss of swift heavy ions. |
