Substrate temperature effects on optical properties and constants of ZnO
(Universiti Malaysia Perlis (UniMAP), 2019-07)
The preparation process of ZnO TCO (Transparent Conducting Oxide) thin films have been conducted in this paper. A Q-switched Nd:YAG laser of 7 ns duration and 1 joule of energy was utilized to perform the deposition process ...
Optical, electrical and photovoltaic studies of γ-MnS thin films deposited by spray pyrolysis technique
(Universiti Malaysia Perlis (UniMAP), 2019-07)
γ-MnS thin films were prepared on glass substrate by spray pyrolysis method at 280 °C. The optical constants and thickness of the films were extracted using the pattern search optimization technique in combination with a ...
Observation of blue shift absorption for surface plasmon resonance in Gold Nano-Islands
(Universiti Malaysia Perlis (UniMAP), 2019-07)
Controllable and predefined absorption are essential in the synthesis of new optoelectronic devices. In this work, an ion coater unit with a modified chamber is used to sputter the gold nano-islands onto glass substrates. ...
