In this work, we investigate the effect of band structure anisotropy and channel orientation on SRS in non-planar channels such as tri-gate and GAA structures. A new formalism is introduced for calculating SRS rates for non-planar structures. The formalism is an extension of the theory by Prange and Nee for planar structures, which has been widely used for calculating the conductivity of inversion layers and thin films. We derive matrix elements for open and closed surfaces of arbitrary shape… CONTINUE READING
