It is usually said that diffusion current cannot overcome potential barrier of 0.1 V. What exactly defines its ability to overcome potential barrier? As concentration of carriers grows, could they overcome barrier more easily? And if not, does it mean that carrier's density could increase up to infinity and still be locked by low potential barrier?
