A _metal-insulator-semiconductor junction_ or an _MIS_ junction is a [junction](Junctions.md) composed of a [metals](Metals), [semiconductor,](Semiconductors) and an [insulator](Insulators) between them. No [current](Electrical%20current) flows between between the metal and semiconductor and thus such junctions always act as [Capacitors.](Capacitors) # MIS junctions at equilibrium # Band bending MIS junctions ## Impact of defects on band bending %%Something I encountered on the Coursera course on this topic is that band banding is only due to defects in MIS junctions, however, I would expect that there is also band bending that results from the particular properties of the metal or semiconductor due to the electric fields in each. this needs to be cleared up.%% ## MIS junctions under bias ### Accumulation case ### Depletion case ### Inversion case #QuantumMechanics/MultiParticleQuantumSystems/SolidStatePhysics/Junctions #QuantumMechanics/MultiParticleQuantumSystems/SolidStatePhysics/Semiconductors #Electromagnetism/Electronics
