Optical properties viz. refractive index ( n ), extinction coefficient ( k ) has been studied by analyzing the transmission spectrum of thin films of Ge17Se83-xInx (x = 0, 3, 6, 9, 12, 15). The spectrum was obtained in the range 400 – 1500 nm. Tauc’s extrapolation has been used to determine optical band gap of thin films. The variation in the optical parameters for different thin films are explained on the basis of presence of defect states and change in average bond energy of the system. The real and imaginary parts of dielectric constants and optical conductivity of the thin films has also been calculated..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
