Fe2o3 Nanoparticles

In this work, ?-Fe2O3 nanoparticles (NPs) have been synthesized by using a simple Pechini sol-gel method from iron nitrate, citric acid as complexing agent and ethylene glycol as polymerization agent. The calcined ?-Fe2O3 NPs were fully characterized by different techniques. It was confirmed that ultrafine and highly crystalline ?-Fe2O3 NPs with high purity and mesoporous nature can be obtained after calcination at 550?C for 3 h. In addition, the results of electrical resistance measurements of the fabricated Fe2O3 thick films showed that ?-Fe2O3 thick films have stable electrical properties which are beneficial for electrical applications such as gas sensing and field effect transistors.

Abstract We report the fabrication and the electrical characterization of back-gated field effect transistors with black phosphorus channel. We show that the hysteresis of the transfer characteristic, due to intrinsic defects, can be exploited to realize non-volatile memories. We demonstrate that gate voltage pulses allow to trap and store charge inside the defect states, which enable memory devices with endurance over 200 cycles and retention longer than 30 minutes. We show that the use of a protective poly (methyl methacrylate) layer, positioned on top of the black phosphorus channel, does not affect the electrical properties of the device but avoids the degradation caused by the exposure to air.
