Green thin film for stable electrical switching in a low-cost washable memory device: proof of concept

Abstract

Low-cost and washable resistive switching (RS) memory devices with stable retention and low operational voltage are important for resistive random-access memory (RRAM).

Vibrational and electrochemical studies of pectin—a candidate towards environmental friendly lithium-ion battery development

“…Similar mechanism is also reported for SnO 2 /aerogel hybrid electrode ( 12–14 , 41–43 ). These results indicate pectin holds promise in fast resistive random access memory (RRAM) applications ( 39 , 44 ).…”

Chitosan based dielectrics for use in single walled carbon nanotube-based thin film transistors

“…11,12 Poly saccharides are promising biopolymers that can be used as dielectric materials with tuneable functional groups, nontoxicity and solubility in green solvents like water. Chitosan, [13][14][15] pectin 16,17 and sodium alginate [18][19][20] are examples of polysaccharides with a polyelectrolyte structure consisting of a charged backbone and mobile counter ions. In polyelectrolyte-gated transistors, by applying a voltage between the gate and source electrodes, the dielectric becomes polarized and forms an electrical double layer at the interfaces, leading to charge carrier generation in the semiconducting channel between the source and drain electrodes.…”

Two-stage filamentary mechanism in high-performance organic resistive switches

“…However, a material that can satisfy all requirements for non-volatile memory for real-world applications, including low threshold voltage, high endurance, long retention, high on/off ratio, and durability is yet to be identified. However, the majority of studies highlight only a few desirable qualities; for example, some have a high on/off ratio with long retention but have poor endurance cycling and high operating voltages, [33][34][35][38][39][40] whereas others have a long retention but a low on/off ratio and poor endurance and high operating voltages 37,[41][42][43] (Table S1, ESI †).…”

“…44 Derivatives of PDIs have been demonstrated as a viable transparent and biodegradable material for flexible organic electronics. 29,[34][35][36][37][38][39][40]45 One such derivative is iso-propyl phenyl perylene diimide (iPrP-PDI), in which the iPrP group works as a donor and the PDI core acts as an acceptor center. 46 The iPrP end group interactions with the perylene core give structural control and functionality for organic electronics applications.…”
