Which outcome results when a semiconductor's band gap narrows under strain?

💡 Explanation

Increased conductivity occurs because decreased band gap leads to increased electron excitation, which triggers higher carrier concentration via Tunneling. Therefore, current flow rises, rather than other properties changing, depending of the doping/band structure.
