Nanosecond time-resolved RIC in some 30 polymers excited by a 40 ns, 8 MeV electron pulse has been studied. Irradiation was carried out in vacuum a t room temperature. For some polymers comparative investigations in the microsecond time region are also reported. Data analysis is based on the concept of geminate electrons controlling pulsed conductivity. It is shown that the application of the dispersive transport formalism allows to gain valuable information concerning the initial effective mobility and the frequency factor directly from the experiment. Die zeitaufgeloste strahlungsinduzierte Leitfahigkeit yon Polymeren im Nanosekundenbereich Die strahlungsinduzierte Leitfahigkeit von mehr als 30 Polymeren nach Anregung durch einen Elektronenimpuls (40 ns, 8 MeV) wurde im Nanosekundenbereich untersucht. Die Bestrahlung erfolgte im Vakuum bei Zimmertemperatur. An einigen Polymeren wurden auch vergleichende Untersuchungen im Mikrosekundenbereich durchgefiihrt. Die Analyse der Meliwerte erfolgt auf Basis des Konzepts der durch die erzeugten Ladungstragerpaare kontrollierten Leitfahigkeit. Es wird gezeigt, daD unter Zugrundelegung des Modells eines dispersiven Ladungstransports wertvolle Informationen uber die effektive Anfangsbeweglichkeit und zum Frequenzfaktor unmittelbar aus dem Experiment erhalten werden konnen.

Time-Resolved Radiation-Induced Conductivity of Polyimide and Its Description Using the Multiple Trapping Formalism

et al. 2019

Polymer dielectrics subjected to intense radiation fluxes exhibit a radiation-induced conductivity (RIC). Polyimide is a good dielectric with excellent mechanical and thermal properties featuring high radiation resistance currently widely used in the spacecraft industry. Its RIC has been extensively studied in several laboratories. The purpose of the present study is to make a direct measurement of the RIC for both pulsed and continuous irradiation using a current sensing technique, which is contrary to the indirect method employing a surface-potential decay technique that is now preferred by spacecraft charging engineers. Our experiments are done in a small-signal regime excluding any recombination and dose effects. In combination with existing computer codes, we managed to develop further the conventional multiple trapping formalism and the RIC theory based on it. The main idea is to supplement an exponential trap distribution responsible for a dominant dispersive carrier transport in polymers with a small concentration of inherent deep traps which may or may not have an energy distribution. In line with this reasoning, we propose a tentative set of RIC model parameters for polyimide that accounts for the observed experimental data. The findings and their implications are discussed in a broad context of previous studies.

Manganese and donor‐acceptor luminescence in ZnSe is investigated by optically detected magnetic resonance (Odmr). Resonances due to the Mn2+ ground state are observed not only in the 4T1 → 6A1 emission band of Mn2+ but in two donor‐acceptor recombination bands. Possible mechanisms for the transfer of the ground state resonance to the excited states are discussed. Cross relaxation is the most probable effect. Moreover, spin memory manifests itself in the influence of the excitation polarization on ODMR signals.
