We investigate the propagation of laser-induced hypersound waves in polycrystalline diamond films by analyzing the spatial changes in the phase and amplitude of the probing laser beam reflected from the surface. We show that the velocity of bulk (lon

A polycrystalline diamond film is grown on a 2 inch Si substrate using a microwave-plasma chemicalvapor-deposition technique. The high quality of the diamond films is confirmed by Raman spectra. A multiple-step procedure is used for local etching of

Homoepitaxial diamond growth may proceed with stops and resumptions to produce thick (a few millimeters or even larger) crystals or structures with different layers (e.g., doped and intrinsic diamonds). Here, we studied the effect of interrupting and
