  Bipolar resistive switching using organic molecule is very promising for
memory application owing to their advantages like simple device structure, low
manufacturing cost, their stability and flexibility etc. Herein we report
Langmuir-Blodgett and spin-coated film based bipolar resistive switching
devices using organic material indole derivative. Pressure - area per molecule
isotherm, Brewster Angle Microscopy, Atomic Force Microscopy and Scanning
Electron Microscopy were used to have an idea about organization and morphology
of the organic material onto thin film. Based on device structure and
measurement protocol it is observed that the device made up of 1 shows
non-volatile Resistive Random Access Memory behaviour with very high memory
window, data sustainability and repeatability.Oxidation-reduction process as
well as electric field driven conduction are the key behind such switching
behaviour.Due to very good data retention, repeatability, stability and high
device yield the switching device designed using compound 1may be a potential
candidate for memory applications.
