From: Mapping thermal conductivity across bamboo cell walls with scanning thermal microscopy
Our setup (a) enabled simultaneous acquisition of conventional AFM topography micrographs (b,c) alongside SThM thermal images (d,e). Micrographs were captured at cross (a,b,d) and radial (a,c,e) sections of bamboo, as shown, to image thermal conductivity differences between cell wall layers in the longitudinal and transverse directions. In general, higher output voltage [V] implies lower thermal conductivity [W/m·K].
