Giant Change in Electrical Resistivity Induced by Moderate Pressure in Pt(bqd)2 – First Candidate Material for an Organic Piezoelectronic Transistor (OPET)

Autor: Sergejs Afanasjevs, Helen Benjamin, Konstantin Kamenev, Neil Robertson

Publikováno v: Advanced Electronic Materials, Vol 10, Iss 3, Pp n/a-n/a (2024)

Abstract The piezoelectronic transistor (PET) has been proposed to overcome the voltage and clock speed limitations of conventional field‐effect transistors (FET). In a PET, voltage is transduced to stress, which leads to an insulator‐metal trans
