Mathematical proof why crystallographic plane (111) is better for microelectromechanical sensors sensing elements
In this research we have obtained mathematical relations between elastic constants, such as Young’s modulus and Poisson’s ratio, using single-crystalline silicon as an example. When the obtained relations are fulfilled, the influence of misalignment of the crystallographic directions and the Подробнее…
