Within the framework of adiabatic approximation , the energy levels and direct interband light absorption in a strongly prolated ellipsoidal quantum dot are studied. Analytical expressions for the particle energy spectrum and absorption threshold frequencies in three regimes of quan-tization are obtained. Selection rules for quantum transitions are(More)
Plasma-enhanced chemical vapor deposition technology has been elaborated for obtaining diamond-like carbon (DLC) coatings of a wide range of properties. Alternative and direct bias voltages have been applied on the substrate, and refractive index dependencies upon various deposition technological parameters have been investigated. The frequency of the bias(More)
