Dynamic RKKY interaction between magnetic moments in graphene nanoribbons
F. S. M. Guimarães, J. Duffy, A. T. Costa +2
Graphene has been identified as a promising material with numerous applications, particularly in spintronics. In this paper we investigate the peculiar features of spin excitations…
Theoretical evaluation of [V(α-CS)] as nuclear-spin sensitive single-molecule spin transistor
Salvador Cardona-Serra, Alejandro Gaita-Ariño, Maria Stamenova +1
In a straightforward application of molecular nanospintronics to quantum computing, single-molecule spin transistors can be used to measure and control nuclear spin qubits. A jump…
First-principles spin-transfer torque in CuMnAsGaPCuMnAs junctions
Maria Stamenova, Razie Mohebbi, Jamileh Seyedyazdi +2
We demonstrate that an all-antiferromagnetic tunnel junction with current perpendicular to the plane geometry can be used as an efficient spintronics device with potential high fre…
Programmable graphene doping via electron beam irradiation
Yangbo Zhou, Jakub Jadwiszczak, Darragh Keane +3
Graphene is a promising candidate to succeed silicon based devices and doping holds the key to graphene electronics. Conventional doping methods through surface functionalization o…
Temperature Dependent Luminescent Decay Properties of CdTe Quantum Dot Monolayers: Impact of Concentration on Carrier Trapping
Graham P. Murphy, Xia Zhang, A. Louise Bradley
We have investigated the temperature dependence of the photoluminescence spectra and average photoluminescence decay rate of CdTe quantum dot monolayers of different sizes as a fun…
Impurity invisibility in graphene: Symmetry guidelines for the design of efficient sensors
John Duffy, James A Lawlor, Caio Lewenkopf +1
Renowned for its sensitivity to detect the presence of numerous substances, graphene is an excellent chemical sensor. Unfortunately, which general features a dopant must have in or…
