For the sample shown in the lower diagram, n = - (v/L)/(u/L) = -(v/u). Many materials have isotropic elastic properties and consequently there are relationships linking the elastic constants discussed ...

Isotropic wet etching occurs when the etch rate is equal in ... Anisotropic wet etching is a common method for fabricating nanowires from various materials, such as silicon, germanium, or III-V ...
