網頁Since the emitter is always roughly 700mV below the base, we also call this "emitter follower" because the emitter output follows the base input. Three terminals means three types: common emitter, common base, common collector/emitter follower. This applies to a MOSFET as well, common source, common gate, common drain/source follower. 網頁2024年4月13日 · However, whereas I i + compensates n-type doping by electron capture, the noble-metal interstitials act as quasi-stable n-dopants. Experimentally, we characterize voltage-dependent, dynamic doping by current density-time ( J-t ), electrochemical impedance, and photoluminescence measurements. 網頁The BJT is constructed with three doped semiconductor regions ( emitter, base, and collector) separated by two pn junctions.
