Their ion-transport characteristics display ionic conductivity of ~0.3/Ω cm (RbAg4I5, 300 K) and activation energy of Ei~0.1 eV.
This determines the temperature-dependent concentration of mobile ions ni~Ni x eEi/kBT capable to migrate in conduction channels at each moment (Ni~1022/cm3, ni~2x1020/cm3, 300 K).
The Rubidium silver iodide–family is a group of AdSIC compounds and solid solutions that are isostructural with the RbAg4I5 alpha modification.
[2][3][4][5][6][7] RbAg4I5 AdSIC displays peculiar features of crystal structure and dynamics of mobile ions.
[8][9][10] Recently, all solid state micrometre-sized supercapacitors based on AdSICs (nanoionic supercapacitors) had been recognized as critical electron component of future sub-voltage and deep-sub-voltage nanoelectronics and related technologies (22 nm technological node of CMOS and beyond).
