Fig. 4.13 A p-n junction rectifier has both p - and n -type regions (A). With a forward bias (B) both electrons and holes move toward the junction, allowing current to pass. With a negative bias (C) the region near the junction becomes depleted in carriers so no current can flow. Source More

... circuits. They are composed of a series of complementary (C-) MOS transistors as shown in Fig. 8 . It is important to take into account, that in real inverters the different signal intensity of p-und n-FET may have an influence when the PE contribution of the nFET and when the pFET is dominant. In high...

drain/source junctions and the N and P – Well junctions. The scanning probe tip is grounded and current flows either into or out of the contacts to the probe tip based on the polarity of the silicon bias. The drain/source contacts for the nfet (dark) and pfet (white) are visible due to the current flow. More

For nfets, a positive voltage reverse biases the Source/Drain junctions. No current flows through the Source, Drain More
