Conventional silicon devices are fabricated in the diamond cubic phase of silicon, so-called Si-I. Other phases of silicon such as Si-XII and Si-III can be formed under pressure applied by nanoindentation and these phases are metastable at room temperature and pressure. We demonstrate in this letter that such phases exhibit different electrical properties to normal (diamond cubic) silicon and exploit this to perform maskless, room temperature, electrical patterning of silicon by writing both...[Show more]
