Figure 3From: Thermal conductivity of highly porous Si in the temperature range 4.2 to 20 KPorous Si SEM images used for the calculation of Hausdorff dimension. Examples of cross-sectional SEM images (a 1 ) and top view images (b 1 ) of the studied porous Si layer with their corresponding binary images (a 2 ) and (b 2 ), used for the calculation of the box counting dimension.Back to article page
