A Supramolecular Gel of Oxalic Acid‐Monoethanolamine for Potential Schottky Barrier Diode Application

Abstract

Abstract A functional supramolecular gel of oxalic acid and monoethanolamine (OXMEA) has been achieved through direct instant mixing of N,N‐dimethyl formamide (DMF) solution of oxalic acid and pure monoethanolamine at room temperature under ambient condition. The rheological analysis established the viscoelastic semi‐solid type nature of mechanically stable OXMEA supramolecular gel. The morphological pattern, imaged through field emission scanning electron microscopic investigation, explores the bean‐seed like hierarchical architecture of the gel network. The semiconducting property of the gel was verified from band gap energy and conductivity estimation. The electrical charge transport property was also analyzed in the form of OXMEA gel based metal‐semiconductor junction thin film device. The obtained nonlinear current‐voltage characteristics of the device signify Schottky barrier diode nature of the synthesized gel. Overall, this work has been proof of development of semiconducting electronic device by OXMEA gel based gel medium.
