It can be smashed into other particles (and is done regularly). A hole, at the physical level, is merely an absence of a physical particle. Now if you call the electron a wave, then yes a hole is as real as the electron. But then the electron isn't real either, it's merely a possibility.

NettetA bipolar transistor is one whose operation depends on both electrons and holes. It comprises two diodes back to back sharing a common central layer. One of the outer terminals is the Collector C and the other is the Emitter E. The central connection is the Base B, and it is part of both the CB and BE diodes.

Nettet13. mai 2005 · Electricity is the flow of electrons through a conductor. Electrons are negatively charged. The actaul flow of electrons is opposite to what conventional current flow is taught. But this is how it works: As an electron 'hops' from one atom to another (in the direction towards a positive charge), it leaves behind a 'hole'. Nettet2. jan. 2012 · As an electron leaves its orbit, the hole is promptly filled by another electron. So as electrons flow one way, the holes "flow" in the opposite direction. While classified as a "hole", it doesn't ... Nettet5. mai 2013 · At major universities throughout the USA, conventional current is used. When studying the current within semiconductors, they use both electron and hole flow, depending on the doping. Electron flow is taught in some smaller, lower level, schools, but it is a tragedy since once they go into industry, they are the minority, and can get … おしとやか 意味 漢字
