From: One-step fabrication of porous GaN crystal membrane and its application in energy storage
Electrochemical performance tested of GaNPM in two-electrode mode: (a) areal capacitance at different current density and scan rates; (b) cycling performance at 5 mA cm−2, where the inset is GCD curve at the initial stage and after 10,000 cycles; (c) Nyquist plots at the initial stage and after 10,000 cycles; and (d) areal energy versus power densities compared with the selected previous reports7,37,51,52,53,54,55,56,57,58.
