Knotek and coworkers [69,701 investigated the dimensionality of conduction in amorphous semiconductor films. When the film was thick (>400 nm), 3D conduction was observed, whereas in thinner films conduction was two-dimensional. They suggest that when the film thickness becomes small relative to the hopping distance (thin films), conduction is constrained to two dimensions. In contrast, when the film thickness is large relative to the hopping distance (thick films), conduction occurs in three dimensions. 

The influence of thermal wave is more signiflcant for thermal conduction in microscale systems compared to macrosystem. An example of thin film conduction is illustrated here to justify this point. Figures 8.13 and 8.14 compare the conduction through a thin film and thick film, respectively. Here, the film is initially at temperature Tq. There is a sudden change in the temperature of both sides to T. The nondimensional variables for the problem are defined as...
