Interestingly, it is found that the contributions of different host atoms (Cu and O) away from anion (N) and cation (Fe) dopants to the variation of near band gap electronic structure of the co-doped Cu2O are different. Moreover, co-doping reduces the band gap and increases the visible-...
Annealing of TiO2 single crystal surfaces in vacuum followed by exposure to oxygen has been discussed in terms of movement of the cation and anion species [24], [25], [26], among which a bulk-assisted reoxidation process is most widely accepted. For example, scanning tunneling microscopy (ST...
nanostructure, having general formula [M2+1-xM3+x(OH)2]y+(Az−)·nH2O where M2+ is divalent cation (commonly Ca2+, Mg2+, Ni2+, Zn2+or Co2+), M3+ is trivalent cation (commonly Al3+ or Fe3+), and A is a charge-balancing anion (commonly CO32−, or NO3−) [34,35]. ...

The ratio of the Cu2O and the In2O3 are 1:1 which are same as ratio of cation and anion of the CuInO2 thin film.LEE, JOON HYUNGHEO, YOUNG WOOLEE, JONG CHULKIM, JEONG JOOUM, SE YOUNG
It is found that bulk Cu2O, Cu/O-terminated Cu2O(111) and (110) surfaces have no magnetic moment, while, the O-terminated Cu2O(100) and polar O-terminated Cu2O(111) surfaces have magnetism. For low index surfaces with cation and anion vacancy, we only found that the Cu vacancy on the...

The carrier concentration in these materials is controlled not only by cation substitution but also by anion substitution.doi:10.1088/0953-2048/15/6/306G. C. CheG. D. LiuZ. A. RenC. DongH. ChenY. M. NiS. L. JiaZ. X. Zhao
The positions of the ions in unit cell are as following: 1(Ca, La) disorderly occupy 1(d) equivalent point position; 1 Tl cation occupies 1 (a) equivalent point position; 2 Cu cations occupy 2(g) equivalent point position with z = 0.365; 2 Sr cations occupy 2(h) equivalent point ...
It should be noted that, as in most binary oxides, Cu cation diffusion coefficients in Cu2O and CuO are much faster than the respective oxygen anion diffusion coefficients (up to 5 orders of magnitude at 1000 °C) [37], [41], [42]. For example, the Cu self-diffusion coefficient in ...
