表面能是固体最基本的参数之一，因为它直接取决于材料的结合力。事实上，它是一种测量沿着平面将材料分成两部分所需的功的量度。由于测量和解释的困难，很少有人对这个量进行测量，而这些测量是通过间接方法进行的。本文报道了用解理技术直接测量Ge和Si的比表面能。通过测量“以可逆方式”移动裂纹所需的力，可以获得表面能。Ge和Si的{111}面的测量值分别为1060ergs/cm2和1230ergs/cm2。由这些测量值可以估算出{100}面和{110}面的能量。它们是：
Surface energy is one of the most fundamental parameters of a solid since it depends directly on the binding forces of the material. Indeed, it is a measure of the work necessary to separate a material into two parts along a plane. Very few measurements have been made of this quantity and these by indirect means, because of difficulties of measurement and interpretation. This report deals with a direct measurement of specific surface energy of Ge and Si made by the cleavage technique. By measuring the force just necessary to move a crack" in reversible fashion" the surface energy can be obtained. The measured value for the {111} planes of Ge and Si are 1060 ergs/cm 2 and 1230 ergs/cm 2. From these measured values the energy of the planes {100} and {110) can be estimated. They are:
