It is the only CC segment with a significant percentage of unmyelinated fibers and also has the greatest percentage of small myelinated axons which appear to be involved in the interhemispheric transfer of information between prefrontal association areas [69]. The slower conduction velocity of these...
meaning that the large energy difference between them prevents Klemens decay. This is a critical factor, because when the decay of optical phonons is suppressed, a phonon bottleneck is created and hot carriers tend to have a longer lifetime. HfN is a conductive ceramic with no electronic bandgap...
