01 Aug 2018TL;DR: It is shown that multilayer hexagonal boron nitride (h-BN) can be used as a resistive switching medium to fabricate high-performance electronic synapses, enabling the emulation of a range of synaptic-like behaviour, including both short- and long-term plasticity.
Abstract: Neuromorphic computing systems, which use electronic synapses and neurons, could overcome the energy and throughput limitations of today’s computing architectures. However, electronic devices that can accurately emulate the short- and long-term plasticity learning rules of biological synapses remain limited. Here, we show that multilayer hexagonal boron nitride (h-BN) can be used as a resistive switching medium to fabricate high-performance electronic synapses. The devices can operate in a volatile or non-volatile regime, enabling the emulation of a range of synaptic-like behaviour, including both short- and long-term plasticity. The behaviour results from a resistive switching mechanism in the h-BN stack, based on the generation of boron vacancies that can be filled by metallic ions from the adjacent electrodes. The power consumption in standby and per transition can reach as low as 0.1 fW and 600 pW, respectively, and with switching times reaching less than 10 ns, demonstrating their potential for use in energy-efficient brain-like computing. Vertically structured electronic synapses, which exhibit both short- and long-term plasticity, can be created using layered two-dimensional hexagonal boron nitride.

TL;DR: Platinum disulfide (PtS2), a new member of the group-10 transition-metal dichalcogenides, is studied experimentally and theoretically and can be explained by strongly interlayer interaction from the pz orbital hybridization of S atoms.
Abstract: Platinum disulfide (PtS2 ), a new member of the group-10 transition-metal dichalcogenides, is studied experimentally and theoretically. The indirect bandgap of PtS2 can be drastically tuned from 1.6 eV (monolayer) to 0.25 eV (bulk counterpart), and the interlayer mechanical coupling is almost isotropic. It can be explained by strongly interlayer interaction from the pz orbital hybridization of S atoms.

TL;DR: It is analytically show that delivery lead time strongly influences the manufacturer's and the retailer's pricing strategies and profits, and the difference between the demand transfer ratios in the two channels with respect to delivery leadTime and direct sale price, customer acceptance of the direct channel, and product type have great effects on the lead time and pricing decisions.
