A technology has been developed for the preparation of thin films of the Bi2Te2.7Se0.3 solid solution through the thermal evaporation in a vacuum using the “hot-wall” method. The high quality of the thin films thus prepared has been confirmed by the X-ray diffraction and Raman scattering data. The electron transport has been investigated over wide ranges of temperatures (1.4–300 K) and magnetic fields (up to 8 T). It has been assumed that the observed weak antilocalization is associated with the dominant contribution from the surface states of a topological insulator. The dephasing length has been estimated. 相似文献

The inverse problem of the scattering theory for Sturm–Liouville operator on the half line with boundary condition depending quadratic on the spectral parameter is considered. Scattering data are defined, some properties of the scattering data are examined, the main equation is obtained, solvability of the integral equation is proved and uniqueness of algorithm to the potential with given scattering data is studied.

Reaction of addition of acrylic acids to 5-acetoxy- and 5-acetoxymethylnorborn-2-ene in the presence of a BF3·O(C2H5)2 catalyst was studied in order to synthesize mixed acetic-acrylic acid diesters of norbornane-2,5-diol and (2-hydroxynorborn-5-yl)methanol,
which are new monomers for syntheses of polymers. 相似文献

Conclusions The dimethylamide of 3-phenyl-3-chloro-2-ketopropionic acid reacts with Ph3P to give -(N,N-dimethyloxamoyl)benzyltriphenylphosphonium chloride. In the presence of methanol, this reaction gives dimethyl(phenylpyruvoyl)amide and Ph3PO.2. The methyl ester of 3-phenyl-3-chloro-2-ketopropionic acid reacts with Ph3P to give methoxycarbonylstyryloxytriphenylphosphonium chloride, which, upon heating in benzene at reflux, gives methyl -chlorocinnamate and Ph3PO.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1395–1396, June, 1989. 相似文献
