Lecture 4
... Si is a semiconductor material with 4 electrons in the outer shell. These 4 electrons occupy 4 sp3 hybrid orbitals with a tetrahedral arrangement. This gives rise to a full valence band (VB) and an empty conduction band (CB) at absolute zero with an energy gap of 1.17 eV between the two. This energy ...

Thermodynamics: Notes
... A closed system is one where there is no exchange of matter. An equilibrium state is one in which all the bulk physical properties of the system are uniform throughout the system and do not change with time. An equilibrium state will be labelled by the symbol . Two variables are required to specify ...
