Acoustic Phonons in Nanowires with Embedded Heterostructures

Figure 6

The normal and shear strains and of the lowest longitudinal and flexural modes respectively in a cross-section taken in the middle of an InAs nanowire and an InAs/InP nanowire heterostructure with  nm along , where the region shown includes two barriers and the quantum well in the heterostructures (calculations in isotropic approximation).
