Abstract :
The authors have presented a new electrical method to investigate the molecular dynamics in polar and non-polar materials at nanoscopic level. During a charging process electric charge is injected in material, in other words the structure is decorated with space charge. During the subsequent heating of the sample we are observing an apparent peak and the genuine peaks that are related to charge detrapping determined by the molecular movement. The method allows to reveal details that are not observed when other electrical and nonelectrical techniques are employed. The parameters for local and collective molecular movements can be determined.
