Pulsed Laser Deposition (PLD) technique has been employed to deposit Diamond Like Carbon (DLC) films with modified parameters on germanium, silicon and glass substrates. A target of graphite was ablated by pulsed laser of 355 nm at room temperature with high repetition rate of 30 Hz. At 300mJ laser energy, 30Hz rate, 20oC temperature and 3.8cm substrate to target distance, good adhesive properties of the DLC films deposited on three different substrates were occurred under the same environment. Intensities ratio ID/IG of the D (for disorder-induced mode) and G (for Raman-allowed graphite-mode) bands were determined. The increase in transmission was observed in near infrared (NIR) and far infrared (FIR) region after depositing DLC coatings on Ge and Si substrates. Atomic force microscopy (AFM) and x-ray diffraction (XRD) were used for the study of surface morphology and structural properties. Various physical properties were determined.

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.
