A hybrid GaN/Ga2O3 structure anchored on carbon cloth as a high-performance electrode of supercapacitors

“…Due to the high carrier mobility and exceptional chemical stability, GaN has also exhibited great potential as an SC electrode material to effectively overcome the issues mentioned above for other metal nitrides. [9][10][11][12] Symmetric SCs based on single-crystal GaN mesoporous membrane electrodes have shown high rate capability, stable cycling life, and ultra-high power density. 9 A composite electrode of GaN nanowire (NW)/graphite paper (GP) also exhibited excellent performance with a specific capacitance of 237 mF cm −2 at 0.1 mA cm −2 and 98% capacitance retention after 10 000 cycles.…”

“…S1 †). 11,20 Furthermore, for the Scheme 1 Formation mechanism displaying the synthesis scheme. ZCO and G-ZCO samples, the peak centered near 560 and 660 cm −1 was associated with the spinel structure and F 1u vibration modes.…”

“…Metal nitrides are suitable electrode materials for superior and durable energy storage devices because of their excellent electrical conductivity and high specic capacitance. 10,11 However, the exploration of compounds of group III-V materials as electrodes for supercapacitor devices is still in its infancy.…”

“…Gallium nitride (GaN), a group III-V direct bandgap semiconductor possessing a wurtzite crystal structure, has been widely explored for various stable and long-term optoelectronic and sensing applications due to its high voltage capability and melting point. [11][12][13] In addition, it exhibits superior thermal conductivity, extra charge carriers per volume, excellent electron velocities, and chemical and physical stability, which are the desired traits of a satisfactory electrode material for supercapacitor application. Thus, ZnCo 2 O 4 -GaN (G-ZCO) nanocomposites could be an ideal candidate for durable highperformance energy storage devices.…”

Electrolyte dependent performance of graphene–mixed metal oxide composites for enhanced supercapacitor applications

“…The functionalization of graphene to introduce heteroatoms in its structure leads to the inclusion of pseudo-faradic characteristics which greatly influences the electrical conductivity. Apart from this, functionalization also ensures good wettability and better ionic affinity with the facilitation of good interfacial adhesion between graphene and metal oxide [14]. GO also serves as a conductive porous network for anchoring the uniform distribution of metal oxide nanoparticles.…”
