The characteristics of photon and phonon standing waves in a periodic medium

Description : The main characteristics of the spatial variation of the photon and phonon wave fields at the band gap boundaries are analysed for a one-dimensional medium with periodic optical or acoustic parameters. The derivations are based on symmetry considerations and on analytical results derived from the ba...

Local variations and temperature dependence of optical absorption coefficient in natural IIa type and CVD diamond optical windows

Description : We used the photothermal deflection (PTD) technique working in a collinear mode to measure optical absorption coefficient at the CO2 laser wavelength (10.6 mum) of polished CVD and natural type IIa diamond optical windows. The CO2 pump beam is focused to a spot size of about 100 mum, enabling the lo...

Photochromism of vacancy-related centres in diamond

Description : Optical experiments, involving photoluminescence (PL), the PL excitation and quenching spectra, as well as transmission and its quenching, were used to analyse the photochromic behaviour of some vacancy-related complexes in diamond. The 2.156 eV, 1.945 eV and 1.68 eV optical centres in CVD diamond a...

Transient nucleation on inhomogeneous foreign substrate

Description : Nucleation from the vapor phase on a foreign substrate with a low number of inhomogeneities is studied. Kinetic equations describing the 3D nucleation on active sites are solved numerically. It is shown that the cluster flux (i.e., the rate of; formation of nuclei of a given size) reaches some extre...

CVD diamond films for electronics

Description : Mechanical, optical, thermal and electronic properties of diamond films and chemical vapour deposition (CVD) techniques are briefly reviewed. Some spectroscopical methods for the characterization of CVD diamond films are described (optical absorption, photothermal deflection spectroscopy, Raman spec...

Critical issues in hard PVD and PA-CVD coatings

Description : In this paper the authors address a few - amongst many others - critical issues in hard coatings. These issues are: (1) the development of standardisation techniques for quality assurance and how well laboratory tests can be used for supporting such techniques. As an example fretting wear testing is...
