The present development in the field of electronics is in pursuit of identifying materials that can be used as an alternative to silicon in the futuristic electronic circuits. In order to translate this desire to reality it is predicted that one may be able to construct single molecules that could each function as a self-contained electronic device. Molecular electronics is conceptually different from conventional solid state semiconductor electronics. Deoxyribose Nucleic Acid (DNA) molecules are being forecasted to be suitable candidates for use in Molecular Electronics. DNA, the focus of various scientists for use as next generation electronic material also forms the subject of study in this work. The main aim of this study is targeted on study of DNA Bases- Adenine, Thymine, Guanine and Cytosine for use in nanoelectronic molecular devices. This work is based on studying the HLG’s and the charging effects in DNA bases- Adenine, Guanine, Thymine and Cytosine by studying their anionic and cationic forms. The molecules were explored extensively for their electrical properties by plotting current-voltage characteristics.
