Function SIDENS

Function SIDENS(T) calculates the intrinsic density of silicon (in units of 1/cm

as a function of temperature T (T in K), for T between 0 and 1685 K. For

Function TDELTA

Function TDELTA(T

) yields the temperature increment T

. The result is

returned with the same units as T

, if any. Otherwise, it returns simply the

difference in numbers. For example,

The purpose of this function is to facilitate the calculation of temperature

differences given temperatures in different units. Otherwise, it’s simply

calculates a subtraction, e.g.,

Function TINC

Function TINC(T

,∆T) calculates T

+DT. The operation of this function is similar

to that of function TDELTA in the sense that it returns a result in the units of T

Otherwise, it returns a simple addition of values, e.g.,
