Electron Work Function–An Effective Parameter for In-situ Reflection of Electron Activities in Various Processes

Evidence for 2kF electron–electron scattering processes in Coulomb drag

Measurements and calculations of Coulomb drag between two low density, closely spaced, two-dimensional electron systems are reported. The experimentally measured drag exceeds that calculated in the random phase approximation by a significant, and density dependent, factor. Studies of the dependence of the measured drag on the difference in density between the two layers clearly demonstrate that...

Benchmarking of Siemens Linac in Electron Modes: 8-14 MeV Electron Beams

Introduction: Radiation therapy using electron beams is a promising method due to its physical dose distribution. Monte Carlo (MC) code is the best and most accurate technique for forespeaking the distribution of dose in radiation treatment of patients.Materials and Methods: We report an MC simulation of a linac head and depth dose on central axis, along with profile calculations. The purpose o...

In situ reflection high energy electron diffraction study of dehydrogenation process of Pd coated Mg nanoblades

The near surface structural evolution in dehydrogenation process of air exposed Pd coated Mg nanoblades was characterized in situ from room temperature to 573 K using reflection high energy electron diffraction RHEED . The evolved normalized diffraction intensity and the full width at half maximum of diffraction peaks have been correlated with the growth of crystal and the change in crystal siz...
