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.…
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…
