Structure and charge transport of amorphous $Cu$-doped $Ta_2O_5$ : An ab initio study

16 Mar 2020 Thapa Rajendra Bhattarai Bishal Kozicki M. N. Subedi Kashi N. Drabold D. A.

In this paper, we present ab initio computer models of Cu-doped amorphous Ta2O5 , a promising candidate for Conducting Bridge Random Access Memory (CBRAM) memory devices, and study the structural, electronic, charge transport and vibrational properties based on plane-wave density functional methods. We offer an atomistic picture of the process of phase segregation/separation between Cu and Ta2O5 subnetworks... (read more)
