From: Significantly enhanced thermal conductivity of indium arsenide nanowires via sulfur passivation
Scanning electron microscopy (SEM) images and the measured thermal conductivity of three sets of unpassivated and S-passivated InAs nanowires. The enhancement ratio of thermal conductivity, defined as (κ s − κ un)/κ un, is shown on the right axis of (c, f and i). (a,b,c) for S1; (d,e,f) for S2; and (g,h,i) for S3. The diameters of S1, S2, and S3 are 76 nm, 86 nm, and 88 nm, respectively.
