Valence states of copper ions and electronic structure of LiCu2O2
- 1998
-
Ingår i: Phys Rev B. ; 57:8, s. 4377-4381
-
Tidskriftsartikel (refereegranskat)abstract
- The electronic structure of LiCu2O2 was studied using x-ray emission and photoelectron spectroscopy (valence band and core levels) as well as band-structure calculations in terms of LSDA and LSDA+U approaches. According to the x-ray emission and photoelectron spectra the valence states of the Cu atoms are found to be mixed, i.e. 2+ and 1+.

Tidskriftsartikel (refereegranskat)abstract
- In a population-based study of persons between 75 and 96 years of age, normal old adults (n = 296), patients with Alzheimer's disease (AD; n = 45), and patients with concomitant AD and depression (AD-D; n = 9) were compared on free recall and recognition
