The paper reports the possibilities to utilize the full solar spectrum (UV–NIR) by combining two different materials which have wide transparency over visible and NIR region. Simple vacuum deposition was preferred to produce ZnSe thin films with multiple 2D PbSe submonolayers (ML). Cross sectional TEM image proves the PbSe ML are well in order and has good periodicity at the interfaces of ZnSe layers...
Nanometer-thickness SiGe alloy layers were synthesized by direct Si ion implantation in Ge (100) wafers at different fluences followed by high temperature annealing. The cross-sectional transmission electron microscopy and secondary ion mass spectrometry reveal the formation of a thin Si-rich crystalline layer in the near-surface region. The micro-Raman spectroscopy and X-ray reflectivity techniques...
In this work, we studied the selenization processes of sputtered Cu/In stacked layers with two different kinds of Selenium (Se) sources: Se pellets (A) and an evaporated layer (B). Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Grazing Incidence X-Ray Diffraction (GIXRD) and Raman spectroscopy were used to characterize the selenized films. In the group A, elemental Se...
