Item ANALYSIS OF OPTOELECTRONICS MATERIALS(2017-05-02) ALQURQASH, AYOOB YOUSIF AHMED; Eseller, EfeOptoelectronic is a section of electronics which deals with emitting and detecting of light such as LEDs, solar cells, transistors, photodetectors. These devices synthesis of materials (Silicon, MWCNTs, SWCNTs and Graphene) has a possibility to convert the incident radiation light in to electric power or vice versa. This thesis reviews the analysis of optoelectronic materials in particular for graphene material which represents the latest episode of the explorations of the origin of materials from carbon (graphite, fullerene, CNT, MWCNTs, SWCNTs and Graphene) and highlight the exceptional properties of MWCNTs and graphene by using Raman theory. An implementation, including experiment in a laboratory on MWCNTs sample by using Raman system which inclueds spectrometer with power laser (200mW, 100mW, 50mW) and wavelength 532nm.
