X-ray diffraction study of crystallographic parameters and debye temperature of c60 single crystals
2002
Abstract The cubic lattice parameter value a =1.41568±0.00006 nm of large size C 60 single crystal has been measured and Debye temperature T D =53.9 K from the X-ray scattering spectrum at a fixed temperature was obtained. The microhardness and dislocation structure of the crystals was examined.
The Joining of LiNbO3, Quartz, TlBr-TlI and Other Optical Materials by the Use of Thin Metal Films as Bonding Agents
2000
A method of joining ferroelectric, optical and other non-metallic materials, such as lithium niobate, quartz, TlBr-TlI, glass, etc., at room temperature under a pressure of 0.1÷0.5 MPa is described. The surfaces to be joined are prepared to optical flatness, and indium or lead coatings as bonding agents are used. To obtain clean surfaces, procedures of the coating deposition and sample joining are performed in situ in a vacuum of l0-4 Pa. The strength of the obtained joints is about 20MPa for indium coatings and about 30MPa for lead coatings. It is supposed that attractive surface forces play a decisive role in the contact formation and bonding of the wafers. The method has been applied for…
