Abstract :This study deals with electronic properties of Boron Arsenide nanoribbons using Density function theory (DFT) calculations. Under specific conditions, nanoribbons can be used as Nano-transistors. It is feasible to modify nanoribbons\' electronic properties, such as bandgap and conductivity, by varying their width and edge shape. Source, drain, and gate are basic parts of a conventional field-effect transistor (FET). The channel\'s conductivity can be changed by applying a voltage to the gate electrode. In current research, Boron Arsenide nanoribbons has been investigated as lead electrode of a transistor and stability of the sheet has been confirmed by positive phonon vibrational modes. Utilizing the band structure spectrum, band gap as an electronic property is measured and reported. Different width values for electrodes have been considered and it has represented that the band gap is size dependent and increasing in ribbon’s size to bulk structure, results in decrements in band gap energy valueKeywords : Nanotransistör, , BAs nanoribon, Bant aralığı, Armchair kenar, Yoğunluk Fonksiyonu teorisi
