An examination of the cold tip theory of whisker growth.
examinationofcol00hove.pdf (4.814Mb)Abstract
A new consideration in the growth mechanism of whiskers is examined.
The heat flow due to the shape of the crystal and the thermodynamics
of the growth reaction is believed to be an important factor
in the unidirectional growth observed in whiskers. A computer program
was formulated to model the heat flow as well as a method to
calculate the time necessary for the temperature changes to occur.
It was found that there is substantial reason to believe the whisker
tip is significantly cooler than the sides. This phenomenon is referred
to as the cold tip mechanism which provides a preferential growth site
for reaction at the tip.
