摘要

首次研究了低温下SiGe hbt的逆模操作。在低温下观察到一种新颖的基极电流“平坦化”，并且使用测量和TCAD模拟的结合详细检查了这种不寻常的电流增益增强行为背后的物理原理。

A novel base current phenomenon in SiGe HBTs operating in inverse mode

The inverse mode operation of SiGe HBTs down to cryogenic temperatures is examined for the first time. A novel base current "flattening" is observed at low temperatures, and the physics behind this unusual current-gain enhancing behavior is examined in detail using a combination of measurement and TCAD simulations.
