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. Author
