We report about properties of carbon layers doped with Er3+ ions fabricated by Plasma Assisted Chemical Vapor Deposition (PACVD) and by sputtering on silicon or glass substrates. The structure of the samples was characterized by X-ray diffraction and

In this paper we report on the fabrication and properties of Er3 and Er3/Yb3 doped Polymethylmethacrylate (PMMA) layers. The reported layers were fabricated by spin coating on silicon or on quartz substrates. Infrared spectroscopy was used for an inv

We report about some properties of erbium and erbium/ytterbium doped gallium nitride (GaN) layers fabricated by magnetron sputtering onsilicon, quartz and Corning glass substrates. For fabricating GaN layers two types of targets were used - gallium i

DLC (Diamond-Like Carbon) coatings have been suggested as protective surface layers against wear. However hard DLC coatings, especially those of greater thickness, have poor adhesion to substrates. We have used several ways to increase the adhesion o

Chromium nitride films are known as good protective layers for against both corrosion and wear. These coatings have been studied in detail during recent years. Their protective capability strongly depends on the deposition conditions. A modern method

For this project, CNx films were prepared by the plasma-enhanced chemical vapour deposition (PECVD) method. Two kinds of substrate were chosen for film deposition: Cr–Ni–Mo steel (0.095 C, 17.25 Cr, 12.04 Ni, 2.49 Mo) and silicon. The substrates

Even thqugh the LPE growth of (Al,Ga)As layers is now largely a matter of industrial development or routine, there still remain some problems that need fundamental study. We have pointed to two of them: growth of very thin layers and the influence of

The noise is studied of the radiation emitted by GaAlAs super-LEDs. At frequencies higher than 1 kHz only the shot noise is observed in the super-LED radiation, its spectral density being close to the theoretical value. At lower frequencies (about 10
