Composite insulators have been used in power network systems for more than 20 years in China due to their remarkable anti-contamination performance. Compared to porcelain and glass insulators, the pollution flashover performance of composite insulators is better, whereas their icing flashover performance is still not clearly known. Shed configuration is a key factor that influences flashover voltage...
Composite insulators have been widely used in high voltage transmission lines more than 20 years in China due to their hydrophobic properties, relatively low weight and maintenance costs, and high mechanical strength. Shed configuration is a key factor that influences flashover voltage of composite insulators under icing conditions. In order to study the effect of shed configuration on the flashover...
High mobility III-V compounds is a strong contender for extending high performance logic beyond the 22 nm technology node. However, demonstrations of exceptional III-V performance required device footprints on the mum-scale despite nm-scale gate lengths, in order to avoid source/drain shorting during contact alloying. The scaling of III-V FETs is severely limited by the unacceptably large lateral...
In summary, we successfully demonstrate the unpinning of the Fermi level in n-GaAs through the insertion of an ultrathin insulator to reduce the penetration of MIGS from the metal into the semiconductor. We are able to transform the current from rectifying Schottky behavior, to increased conduction, to tunneling limited, simply by increasing the SiN thickness, verifying the ability for SiN to modulate...
