Abstract

Nonvolatile electrical resistive behaviour was demonstrated for a copper sulfide nanoparticle decorated carbon nitride (CSCN) based device.

“…Carbon nitride exhibited encouraging performance in photocatalytic hydrogen evolution 20 – 22 , sensing 23 and supercapacitor application 24 . Carbon nitride based materials also showed remarkable applications as a support system in organic transformation reaction 25 – 27 , organic photocatalytic reaction 28 , fuel cell 29 and nonvolatile memory 30 , 31 applications.…”

Carbon Nitride Supported Lead Oxide Nanoparticles for Memristor Application: Charge-Transport Mechanism for Resistive Switching

“…For the low conduction state, within the region from −5 to +4.3 V, the device was followed by a Poole–Frenkel emission (PF) mechanism, ln ( I / V ) vs V 0.5 , J PF = q μ N C E exp­((− q (Φ T – ( qE /πε) 0.5 )/ KT ), where q is the electron charge, μ is the electron mobility, N C is the density of states, E is the electric field, J PF is the current density, Φ T is the electrons trap depth, K is Boltzmann’s constant, ε is the permittivity of the material, and T is the absolute temperature, and for the high conduction state (within the range from +4.3 to −3.6 V) the transport behavior of the device was followed by the Ohmic conduction mechanism, ln ( I ) vs ln ( V ), with the slop values of ∼0.96, for both sides, Figure A,B. For further mechanistic discussion, an estimated energy diagram has been proposed in Figure C. − The low conduction state was fitted with a Frenkel–Poole emission model where the charge carriers were moved forward by a trap-assisted electron transport process through an electrical insulator (carbon nitride), Figure D. The electrons are generally trapped in different localized states and then overcome due to the gradual increase of applied electric field and finally reache the conduction band of carbon nitride through a bulk-limited conduction process.…”

Electrical response of organic molecule supported preformed and in situ formed antimony sulfide nanoparticles under frequency conditions

“…13,14 Copper sulfide embedded carbon nitride thin film based device exhibited nonvolatile resistive switching behaviour and the transport mechanism of the device was followed by Poole-Frenkel and Ohmic behaviour for the OFF-state and ON-state, respectively, with an ON to OFF ratio of 10 4 . 15 The sulfides of other non-transitional elements, such as tin, lead and bismuth sulfides are well explored and exhibited good photocatalytic, photovoltaic and energy storage performances. [16][17][18][19][20][21] Apart from those, antimony sulfide has also getting attention as a potential candidate for anode material in sodium and lithium ion battery applications due to its high specific capacity value.…”
