Physics · Solid State Physics
Consider two crystals, A and B, of identical size and shape, having Debye temperatures θA and θB respectively such that θB / θA = 2. In the low-temperature regime, where thermal conductivity K is limited solely by surface scattering, what is the ratio of their thermal conductivities KB / KA at a given temperature?
