Three-dimensional description of vibration-assisted electron knock-on damage
Alexandru Chirita, Alexander Markevich, Mukesh Tripathi +4
Elastic knock-on is the main electron irradiation damage mechanism in metals including graphene. Atomic vibrations influence its cross-section, but only the out-of-plane direction…
Spontaneous interlayer compression in commensurately stacked van der Waals heterostructures
Nicholas A. Pike, Antoine Dewandre, François Chaltin +4
Interest in layered two dimensional materials, particularly stacked heterostructures of transition metal dichalcogenides, has led to the need for a better understanding of the stru…
Vibrational and dielectric properties of monolayer transition metal dichalcogenides
Nicholas A. Pike, Antoine Dewandre, Benoit Van Troeye +2
First-principles studies of two-dimensional transition metal dichalcogenides have contributed considerably to the understanding of their dielectric, optical, elastic, and vibration…
Calculation of the Anisotropic Coefficients of Thermal Expansion: A First-Principles Approach
Nicholas A. Pike, Ole M. Løvvik
Predictions of the anisotropic coefficients of thermal expansion are needed to not only compare to experimental measurement, but also as input for macroscopic modeling of devices w…
Determining the Optimal Phase-Change Material via High-Throughput Calculations
Nicholas A. Pike, Amina Matt, Ole M. Løvvik
The discovery and optimization of phase-change and shape memory alloys remain a tedious and expensive process. Here a simple computational method is proposed to determine the ideal…
Vibrational and dielectric properties of the bulk transition metal dichalcogenides
Nicholas A. Pike, Antoine Dewandre, Benoit Van Troeye +2
Interest in the bulk transition metal dichalcogenides for their electronic, photovoltaic, and optical properties has grown and led to their use in many technological applications.…
Electron-Beam Manipulation of Silicon Dopants in Graphene
Mukesh Tripathi, Andreas Mittelberger, Nicholas A. Pike +5
The direct manipulation of individual atoms in materials using scanning probe microscopy has been a seminal achievement of nanotechnology. Recent advances in imaging resolution and…
Origin of the Counterintuitive Dynamic Charge in the Transition-Metal Dichalcogenides
Nicholas A. Pike, Benoit Van Troeye, Antoine Dewandre +2
We investigate the chemical bonding characteristics of the transition metal dichalcogenides based on their static and dynamical atomic charges within Density Functional Theory. The…
Magnon Waves on Chains of YIG particles: Dispersion Relations, Faraday Rotation, and Power Transmission
Nicholas A. Pike, David Stroud
We calculate the dispersion relations for magnon waves on a periodic chain of spherical or cylindrical Yttrium Iron Garnet (YIG) particles. We use the quasistatic approximation, ap…
Faraday Rotation, Band Splitting, and One-Way Propagation of Plasmon Waves on a Nanoparticle Chain
Nicholas A. Pike, David Stroud
We calculate the dispersion relations of plasmonic waves propagating along a chain of semiconducting or metallic nanoparticles in the presence of both a static magnetic field ${\bf…
Faraday Rotation and One-Way Propagation of Plasmon Waves on a Nanoparticle Chain
N. A. Pike, D. Stroud
We calculate the dispersion relations of plasmonic waves propagating along a chain of metallic nanoparticles in the presence of both a static magnetic field and a liquid…
Model of the Longitudinal Spin Seebeck Coefficient of InSb in a Magnetic Field
N. A. Pike, D. Stroud
We develop a simple theory for the longitudinal spin Seebeck effect in n-doped InSb in an external magnetic field. We consider spin- electrons in the conduction band of InSb w…
Graphene with adatoms: tuning the magnetic moment with an applied voltage
N. A. Pike, D. Stroud
We show that, in graphene with a small concentration of adatoms, the total magnetic moment can be switched on and off by varying the Fermi energy , either by applying a…
