Thermionic emission assisted charge conduction mechanisms across LaMnO3/La0.7Ca0.3MnO3 interface of manganite thin film structure

In the present communication, temperature dependence of resistive switching (RS) behavior across chemically grown LaMnO3/La0.7Ca0.3MnO3 (LMO/LCMO) interface have been discussed by employing various theoretical approaches and mechanisms. Temperature dependent RS behavior of LMO/LCMO interface highlights impactful switching between high resistance state (HRS) and low resistance state (LRS) under reverse bias mode through an active role of depletion region. Trapping-detrapping processes assisted charge conduction has been identified as a source of RS nature of LMO/LCMO interface. Thermionic emission model and space charge limited conduction (SCLC) mechanism have been employed to understand the charge conduction and charge transport across LMO/ LCMO interface. Present structure of Ag/LMO/LCMO/Ag has also been investigated for possible retention and endurance behaviors under different external parameters which verify the stability, reliability, reproducibility, non-volatile nature and applicability of LMO/LCMO interface.
