Stackable bipolar pouch cells with corrosion

2 metal foils, current travels only a short distance in the through-plane direction of the current collector in the bipolar cell configuration. This shorter path length lowers the effective electrical resistance, making the design suitable for high-power applications.

A novel Horizontal Current Bipolar Transistor (HCBT) is processed with the scaled down dimensions and the improved technology. The active transistor region is built in the defect-free sidewall of the 580 nm wide n-hills in the (1 1 0) wafer, implying the reduction of the parasitic region's volume, i.e. the extrinsic base and the collector. The fabricated HCBT exhibits the cutoff frequency ( f

Bipolar junction transistor

A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and holes as charge carriers. Unipolar transistors, such as field-effect transistors, use only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much larger current flowing between two other
