What is Interface states?

Interface states in the explanations

• The Si/SiO2 interface retains interface states from dangling silicon bonds at about 10¹¹–10¹² cm⁻²eV⁻¹.

  What is the heat treatment called, performed in a hydrogen-…

• Because atomic arrangement differs by crystal plane, MOSFETs mainly use (100) wafers, which have fewer interface states.

  What is the crystal structure of single-crystal silicon?

• The strong field near the drain creates hot carriers that are injected into the gate dielectric or create interface states, shifting threshold voltage and reducing current.

  What is the purpose of the LDD (lightly doped drain) struct…
