The in-plane thermal conductivity ${\mathrm{\ensuremath{\kappa}}}_{\mathrm{\ensuremath{\parallel}}}$ has been measured over the temperature range 5--400 K for samples of chemical-vapor-deposited (CVD) diamond made by both the microwave and hot-filame

The phonon-dispersion curves derived from neutron-scattering experiments performed on diamond [J. Warren et al., Phys. Rev. 158, 805 (1967)] are not accurate enough to yield the exact frequencies of critical-point (CP) phonons and, thus, to provide a

With the advent of new growth techniques, research on the properties of diamond has undergone a rebirth in recent years. The capability of producing very high quality polycrystalline films has greatly enhanced the prospects of exploiting the extreme

We have investigated the thermal conductivity of large diamond samples grown by both hot filament and microwave plasma assisted chemical vapor deposition in order to study in detail the processes limiting heat conduction in this system. For samples c

In polycrystalline CVD diamond of useful macroscopic dimensions, which may be considered for high heat flux applications, thermal conductivity parameters are largely determined by grain size resulting from growth morphology, defects and impurities in

The phono-dispersion curves derived from neutron-scattering experiments performed on diamond are not accurate enough to yield the exact frequencies of critical-point (CP) phonons and, thus, to provide a satisfactory interpretation of second-order opt

Absorption in the 8-12 μm spectral region in diamond films is dominated by single phonon effects due to departures from perfect crystallinity in the deposits. Conditions which maximize crystalline perfection must therefore be chosen to deposit diamo

The atomic structure of amorphous Tb20Fe80 thin films has been studied by Extended X-ray Absorption Fine Structure (EXAFS) of both FeK and TbL III absorption edges. The local site geometry around Fe atoms shows predominantly Fe nearest neighbors with

We have used EXAFS to investigate the local atomic structure and its change with annealing for amorphous, sputtered Tb20Fe80 alloy films. The structural and magnetic properties of these materials are of particular current interest because of applicat

EXAFS is used to measure the local atomic structure of Fe in Au doped Tb-Fe thin film alloys. The as deposited sample shows structural fcatures which are essentially identical to those of the undoped films. Au additions stabilizes the amorphous struc
