Electron correlation satellites were identified in all measured 1s photoelectron spectra of 3d metals and the 1s lineshapes were interpreted by model calculations. In the case of NiFe alloys the charge transfer was derived from the measured alloy-metal Auger parameter shifts, in a satisfactory agreement with model calculations. A method and program package were developed for determining the physical parameters and distributions - characterizing the electron transport in surface layers – from spectra of electrons backscattered from 3d metals. These quantities were applied for evaluating and modeling the measured K-Auger and core photoelectron spectra. A new electron scattering phenomenon (super surface scattering) has been described and confirmed by experiments. A 3D MC model to simulate the charge transport and to aid the derivation of current signal in semiconductor radiation detectors was developed. The model describes the processes limiting the movement of free charge carriers in the detectors in more details than other models. The model and the program was tested for Si pin photodiode, its validity was verified by earlier experimental and MC simulated diffusion and drift data.
