Electronic and thermal conduction properties of halogenated porous graphene nanoribbons
George Alexandru Nemnes, Camelia Visan, Andrei Manolescu
In the framework of density functional theory (DFT) calculations we investigate the electronic and thermal properties of porous graphene (PG) structures passivated with halogen ato…
Time-dependent current into and through multilevel parallel quantum dots in a photon cavity
Vidar Gudmundsson, Nzar Rauf Abdullah, Anna Sitek +3
We analyze theoretically the charging current into, and the transport current through, a nanoscale two-dimensional electron system with two parallel quantum dots embedded in a shor…
Efficient determination of the Markovian time-evolution towards a steady-state of a complex open quantum system
Thorsteinn H. Jonsson, Andrei Manolescu, Hsi-Sheng Goan +4
Master equations are commonly used to describe time evolution of open systems. We introduce a general method for calculating a Markovian solution of the Nakajima-Zwanzig generalize…
Molecular Dynamics Simulations of Field Emission From a Prolate Spheroidal Tip
Kristinn Torfason, Agust Valfells, Andrei Manolescu
High resolution molecular dynamics simulations with full Coulomb interactions of electrons are used to investigate field emission from a prolate spheroidal tip. The space charge li…
In-gap corner states in core-shell polygonal quantum rings
Anna Sitek, Mugurel Tolea, Marian Nita +3
We study Coulomb interacting electrons confined in polygonal quantum rings. We focus on the interplay of localization at the polygon corners and Coulomb repulsion. Remarkably, the…
Dynamic electrical behavior of halide perovskite based solar cells
George Alexandru Nemnes, Cristina Besleaga, Andrei Gabriel Tomulescu +4
A dynamic electrical model is introduced to investigate the hysteretic effects in the I-V characteristics of perovskite based solar cells. By making a simple ansatz for the polariz…
