In Fig. 7.2b, we show only the lowest 12 branches calculated by Thonhauser and Mahan for a seven-ring Si [ 111] nanowire (3 THz corresponds to ˜ 100 cm −1) [ 86 ]. It can be seen that eight of the lowest lying branches are optical and four are acoustic.

WebThe upper branch is the optical branch because it can cross with the (linear) dispersion relation of photons, allowing these phonons to efficiently emit and absorb photons. Like before, the phonon group velocity is v = d ω / d k, and the density of states is g ( ω) = d N / d ω = L 2 π ∑ d k / d ω . http://www.chemistry.uoguelph.ca/educmat/chm729/phonons/optical.htm
