Abstract
A critical review of experimental evidence for thermal transport inhibition is presented. Results of earlier experiments are reconsidered in the light of more recent experimental and theoretical studies. Many of the results which have often been used to substantiate the claim that there is inhibition of the cold electron thermal transport can be explained by other mechanisms, such as ponderomotive force. The most direct evidence for inhibition comes from the interpretation of the X-ray Bremsstrahlung emission. Current ion emission data is not sufficiently refined to provide firm evidence. There is no clear evidence to suggest that the energy flux associated with the hot electrons is inhibited, except for a recent experiment designed purposefully to impede the hot electron flow.
