Only difference is upto which they are occupied and vertical separation between them i.e. energy band gap. Thus energy band may be defined as the gap or region between the valence and conduction the measurement of absorption spectra is the direct method for probing the band structure of semiconductors band. The band gap may be classified as direct and indirect band gap depending upon the electron transition.</Abstract> <AbstractLanguage>English</AbstractLanguage> <Keywords>Forbidden direct transition, Optical properties, Structural properties, Electrical properties, Topography.</Keywords> <URLs> <Abstract>https://ijesm.co.in/ubijournal-v1copy/journals/abstract.php?article_id=4218&title=A DESCRIPTIVE STUDY ON CHARACTERIZATION TECHNIQUES</Abstract> </URLs> <References> <ReferencesarticleTitle>References</ReferencesarticleTitle> <ReferencesfirstPage>16</ReferencesfirstPage> <ReferenceslastPage>19</ReferenceslastPage> <References/> </References> </Journal> </Article> </ArticleSet>
