Abstract: The field of physics continues to be finishing 100s of years in using scientific methods to know fundamental concepts of character, matter and and just how they interact. A Physicist conducts research within an area of physics through interaction with lots of other disciplines. You will find many subjects of physics from really small particle physics to large cosmology or study from the World. During these huge regions of subjects Semiconductor technology plays an important role. The optical and related qualities of couple of II-Mire semiconductors are analyzed within the design and analysis of Opto-electronic products. Various analytical expressions were designed to read the optical constants of echoing index, band energy gap, and absorption coefficient. These are utilized to evaluate variation of echoing index with pressure (dn/dp) and efficient mass of charge service providers in ternary semiconductors and comparison from the results is made from available reported values.

INTRODUCTION: Materials could be categorised directly into conductors, semiconductors and insulators by remarkable ability to conduct electrical current. Semiconductors have resistivity between 10-4

OBJECTIVES: The primary objectives from the research are: – 1) Resolution of Variation of echoing index with pressure (dn/dp), effective mass service providers (m*), Polarizability (aM), width of one’s gap (Eg) of Group II-Mire, Group III-V ternary alloys 2) The physical studies of Group II-Mire and Group III-V are analyzed in literature survey. 3) The dispersion data of those ternary compounds are utilized to evaluate n, that is major element of dielectric polarization can be used to judge band energy gap and in comparison the information on Eg with reported values after which by worrying the significance of dispersion data. 4) The optical polarizability (aM) of Group III-V and Group II-Mire ternary systems are examined from data of echoing indices at various wavelengths with a new dispersion relation if you take the slopes of curves 1/l2 and 1/n-1. These values are utilized to evaluate diamagnetic susceptibility (centimetres), molecular electron ionization mix section (Q). 5) The optical energy gap values at various arrangements (x) of ternary alloy systems were examined in the plots of ahn versus hn. Using a, the optical energy gaps of couple of ternary semiconductors are believed by utilizing (ahn) versus (hn)

METHODOLOGY: Portrayal of Semiconductors is essential like a x of the constituent within the Semiconductors will have significant changes for Eg. CdSxSe1-x, the Y of Sulphur will play much role in electronic distribution and reflect in physical qualities even the qualities like reflectivity which is a vital parameter within the calculation of anti reflecting qualities of mirrors in labels is important, thus the detailed study of physical qualities like polarizability, susceptibility. Electron ionisation mix-section and absorption coefficients are adopted. The power gap, a parameter of for the most part essential in calculating Electrical Optical and Electro Optical qualities can also be stress. The variation from the physical qualities using the % from the constituent resulting in additive character, non-linear contributions if any will also be to become talked about. The secondary data continues to be collected from various released journals

HYPOTHESIS: The Linear variation or the existence of nonlinear batches within the Physical property using the alternation in worth of x, the % from the ingredients is another step to reckon with the existence of non linear contributions if any will probably through light on non linear phenomena in Optical effects.

CONCLUSION: Growth and portrayal of semiconductor films have tossed a lot of helpful info on their usefulness in the style of solar panels, antireflective films etc. The mobility from the electrons and holes in semiconductor are controlled by the power of the dopants. Optical Studies, Magnetic Studies and Allied Electrical Studies of those compounds are attaining importance. The modification of optical qualities with thickness of film brings new facets of understanding between electron contributor and acceptors. This can be a pre requisite for better knowledge of mechanism from the growth and analysis of Nana deposits. As a result it is targeted in our analysis to possess a thorough study of physical qualities of the ternary systems and stretching this idea to Nana Scales.
