Synaptic Characteristics of Amorphous Boron Nitride …

2020-8-28 · In this study, the resistive switching and synaptic properties of a complementary metal-oxide semiconductor-compatible Ti/a-BN/Si device are investigated for neuromorphic systems. A gradual change in resistance is observed in a positive SET operation in which Ti diffusion is involved in the conducting path. This operation is extremely suitable for synaptic devices in hardware-based ...

Preparation of Amorphous Boron Nitride and Its …

Amorphous boron nitride, BN, is obtained from the reaction of B -trichloroborazine, (BCINH)3, with cesium metal. The amorphous product is converted to a turbostratic form upon heating to 1100°C. Scanning electron microscopy reveals a previously unreported morphology composed of hollow tubular structures. The largest of these appear to be approximately 3 micrometers in external diameter and 50 ...

Amorphous boron nitride for vacuum-ultraviolet ...

2020-7-16 · However, in practical application, boron nitride crystals cannot satisfy current requirements in size and quality. In this work, we prepared an amorphous sp 2 bonding BN film by magnetron sputtering with boron as the growth source at a low temperature (500 °C). No harsh conditions of high temperature and pressure are required, but the purity ...
