The concept of hole current in metals is debated, particularly regarding its existence and implications. While electron current is the primary focus, the discussion highlights that when an electron vacates its position, it creates a hole. However, in metals like cadmium, the presence of positive Hall coefficients suggests that hole current can be observed under certain conditions. Ultimately, the consensus is that while holes are a theoretical construct, they do not manifest as physical entities in the same way as electron currents do.
PREREQUISITESPhysicists, electrical engineers, and materials scientists interested in the behavior of charge carriers in metals and the implications of hole current in electronic applications.
keerthana said:we generally talk about electron current in metals.but when an electron leaves, it leaves a hole in its place.
does the hole current really exist in metals?please explain the stuff.
