Given the many and varied roles of ions in living organisms, biocompatible organic ion sensors are a matter considerable interest. In this work, simple, low-voltage, solid-state hygroscopic insulator field effect transistors (HIFETs) have been tested to characterise their ion-sensitive properties. Two biologically relevant salt solutions, sodium chloride (NaCl) potassium (KCl), were tested. To ...

Abstract We report the fabrication and electrical characterization of back-gated field effect transistors with a black phosphorus (BP) channel. show that hysteresis transfer characteristic, due to intrinsic defects, can be exploited realize non-volatile memories. demonstrate gate voltage pulses allow trap store charge inside defect states, which enable memory devices endurance over 200 cycles r...
