|Issue Date:||28-Aug-2000||Citation:||Kuok, M.H.,Ng, S.C.,Zhang, V.L. (2000-08-28). A brillouin study of the angular dispersion of generalized surface and pseudosurface acoustic waves on the (001) surface of InSb. Applied Physics Letters 77 (9) : 1298-1300. ScholarBank@NUS Repository.||Abstract:||The velocity angular dispersion of the generalized surface (GSW) and pseudosurface (PSW) acoustic waves on the (001) plane of InSb has been measured by Brillouin scattering. The complete range of angular dispersion of these waves on the (001) plane of an anisotropic cubic crystal has been experimentally determined. The p-p and p-s polarization results accord well with theory. In particular, the measured angular dispersion of these surface modes traces out two separate and distinct branches, in contrast to one single curve arising from the branching from GSW to PSW, normally observed for anisotropic cubic crystals. © 2000 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/95604||ISSN:||00036951|
