Preparation and properties of ultra-thin film CuGaS2
Abstract：In recent years, due to the widespread demand for ultra-thin films, one of ultra-thin films of research and preparation for the great concern. The method for preparing ultrathin film of roughly three: (1), LB membrane technology; (2), based on self-assembly technology chemisorption; and (3), alternating electrostatic deposition techniques.Alternatively wherein the electrostatic deposition technology because no complicated apparatus, equipment, film thickness controllable and adjustable components and many other advantages, the most widely applied in the preparation of ultrathin films.Because ultra-thin films of quality and efficiency considerations, I-III-VI2 semiconductor film in the normal use of the most common, and CuGaS2 as I-III-VI2 three yuan sulfide copper-based material has a representative, asIt has a wide band gap, the light-emitting device having a green area of potential applications, while the generation and detection of infrared emission also has broad application prospects, and therefore it is also committed to the development of its value in use.In this experiment, we will choose CuGaS2 layer self-assembly method for producing ultra-thin films, and some of the features CuGaS2 studied the optical properties and thermal stability of ultra-thin films.
