Function SIDENS
Function SIDENS(T) calculates the intrinsic density of silicon (in units of 1/cm
3
)
as a function of temperature T (T in K), for T between 0 and 1685 K. For
example,
Function TDELTA
Function TDELTA(T
0
,T
f
) yields the temperature increment T
f
– T
0
. The result is
returned with the same units as T
0
, 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
0
,
∆T) calculates T
0
+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
0
.
Otherwise, it returns a simple addition of values, e.g.,
