Two-To-Four Coherent Beams Interference Patterns Of Non-Orthogonal Planes, Ali̇ekber Aktağ
Two-To-Four Coherent Beams Interference Patterns Of Non-Orthogonal Planes, Ali̇ekber Aktağ
Turkish Journal of Physics
In this paper, we present an analysis of intensity distribution of interference pattern of two-to-four linearly polarized plane waves at their intersection in a plane surface. A configuration in which the four plane waves intersect at different angles along four non-orthogonal planes is considered. We show that the shape and the intensity distribution of the interference pattern is strong function of the angles of planes, kinds of polarizations, beam incidence angles. A variety of two-dimensional intensity distribution arrays have been formed by two-to-four beams with differing plane angles, angles of beam incidence and beam polarizations, which may potentially be useful …

High Field Conduction In Thin Films Of A-(Ge_{.20}{Se0}_{.80})_{1-X}{Pb}_X Glassy Alloys, Rachna Singh, Santosh Kumar
Turkish Journal of Physics
The present paper reports d.c. conductivity measurements at high electric fields in vacuum evaporated amorphous thin films of (Ge_{.20}Se0_{.80})_{1-x}Pb_x (where x = 0, 0.02, 0.04, 0.06 and 0.10) glassy alloys. Current-Voltage (I-V) Characteristics have been measured at various fixed temperatures. In these samples, at low electric fields, ohmic behavior is observed. However, at high electric fields (E \sim 10^4 V/cm), non-ohmic behavior is observed. An analysis of the experimental data confirms the presence of space charge limited conduction (SCLC) in the glassy materials studied in the present case. From the fitting of the data to the theory of SCLC, the …
