Investigation of Optical and Electronic Properties of Iivi Group Semiconductor Nano Materials

Abstract

Nanomaterials are cornerstones of nanoscience and nanotechnology. These are classified as nanoparticles, nanowires, nanotubes, nanolayers and nanopores. Due to unique properties, nanomaterials have gained the attention of scientific community. Nanomaterial plays an important role in the field of science, environment and energy resource in the application of nanotechnology and nanoscience. During the past decades, nanotechnology grabbed the significant attention in the field of science and engineering. Nanomaterial is defined as a material with the size of approximately 1-1000 nanometers. The properties and general behaviour of the nanomaterials is largely dependent on the method to produce a nanomaterial such as top-down and bottom-up methods. In the top-down method, the larger part is used to produce nano-components of the material, and in bottom-up, the nanomaterial is used to produce by processing atom by atom or molecule by molecule. newlineThe construction of every discrete solid-state electronic device or integrated circuit begins with a semiconductor material of the highest quality. Semiconductors are materials whose conductivity lies between that of conductors and insulators. Compound semiconductors are useful in special electronic circuit applications as well as in applications that involve light, such as light-emitting diodes. Semiconductors abundant in optoelectronic properties have produced a lot of research and technological curiosity in current times because of their modernistic applications in different devices such as laser diodes(LDs), photo detectors, integrated circuits, light emitting diodes (LEDs), heterostructure lasers, nanotechnology and optical modulators operating in mid infra-red regions(2-5µm). newlineThe II-VI compounds are being extensively used in infrared detectors, ultra high speed bipolar transistors, optical fiber communications and advanced microwave devices. These materials possess the appropriate direct band gap to produce light emitting diodes and lasers from blue to red
