Published in 2021 at "Advanced materials"

DOI: 10.1002/adma.202103235

Abstract: Silicon chips containing arrays of single dopant atoms could be the material of choice for both classical and quantum devices that exploit single donor spins. For example, group-V-donors implanted in isotopically purified 28 Si crystals… read more here.

Published in 2019 at "Mathematical Methods in the Applied Sciences"

DOI: 10.1002/mma.5555

Abstract: In this paper, we propose a novel class of parametric bounds on the Q‐function, which are lower bounds for 1 ≤ a < 3 and x > xt = (a (a‐1) / (3‐a))1/2, and upper… read more here.

Published in 2017 at "Networks"

DOI: 10.1002/net.21749

Abstract: Broadcasting is a process in which an individual has an item of information which needs to be transmitted to all of the members in a network (which is viewed as a connected graph). k-broadcasting is… read more here.
