Solid State Electronic Devices, 7th Edition

Appendix I Definitions of Commonly Used Symbols¹

¹ This list does not include some symbols that are used only in the section where they are defined. Units are given in common semiconductor usage, involving cm where appropriate; it is important to note, however, that calculations should be made in the MKS system in some formulas.

a	Chapter 1: unit cell dimension (Å); Chapter 6: metallurgical channel half-width for an FET (cm)
a, b, c	basis vectors
A	area (cm2)
ℬ	magnetic flux density (Wb/cm2)
B	base transport factor for a BJT
B, E, C	base, emitter, collector of a BJT
c	speed of light (cm/s)
C	capacitance/area in MOS (F/cm2)
Ci, Cd, Cit	insulator, depletion, interface-state MOS capacitance/area ...
