Optical properties of Se or S-doped hydrogenated amorphous silicon thin films with annealing temperature and dopant concentration

Optical properties of amorphous CuS thin films deposited chemically at different pH values

“…In this process, the total energy and momentum of the electron-photon system must be conserved. The functional dependence of (˛h ) 2 Fig. 7.…”

“…These amorphous thin films are important in various technological areas because they exhibit some of the optical properties of their crystalline counterparts. Similar to other deposited thin films, the properties of amorphous chalcogenide thin films also dramatically depend on their deposition conditions [1][2][3][4][5][6][7]. The deposition of chalcogenide thin films is achieved by vacuum thermal evaporation [8], thermal evaporation [9], the flash evaporation method [10] and chemical bath deposition (CBD) [11].…”

Progress in electrode and electrolyte materials: path to all-solid-state Li-ion batteries

“…Silicon is the second most abundant element in the earth by mass (25.7%) and very rarely occurs in nature as the pure free element [114]. Silicon is one of the principal components of most semiconductor devices such as integrated circuits (ICs) and microchips [40,41,[115][116][117].…”

“…117 Silicon is one of the principal components of most semiconductor devices such as integrated circuits (ICs) and microchips. 42,43,[118][119][120] However, two major scientific and technical challenges have hindered their practical applications in energy storage devices. Firstly, due to the alloying mechanism, a large number of lithium atoms are inserted into Si, breaking the chemical bonds between Si atoms.…”
