The physics of NBTI: What do we really know?

There is no consensus on the basic physical mechanism of Negative Bias Temperature Instability, in spite of thousands of publications over the past half century. There remains fundamental disagreement over whether NBTI is diffusion-limited or reaction-limited. The origins of the two viewpoints are s...

Summary:There is no consensus on the basic physical mechanism of Negative Bias Temperature Instability, in spite of thousands of publications over the past half century. There remains fundamental disagreement over whether NBTI is diffusion-limited or reaction-limited. The origins of the two viewpoints are summarized and some comments on the main controversial aspects of the two leading models are offered.
