Tunable plasmon-enhanced second-order optical nonlinearity in transition metal dichalcogenide nanotriangles
F. Karimi, S. Soleimanikahnoj, I. Knezevic
The development of nanomaterials with a large nonlinear susceptibility is essential for nonlinear nanophotonics. We show that transition-metal-dichalcogenide (TMD) nanotriangles ha…
Density-matrix model for photon-driven transport in quantum cascade lasers
S. Soleimanikahnoj, M. L. King, I. Knezevic
We developed a time-dependent density-matrix model to study photon-assisted (PA) electron transport in quantum cascade lasers. The Markovian equation of motion for the density matr…
Modeling quantum cascade lasers: Coupled electron and phonon transport far from equilibrium and across disparate spatial scales
Y. B. Shi, S. Mei, O. Jonasson +1
Quantum cascade lasers (QCLs) are high-power coherent light sources in the midinfrared and terahertz parts of the electromagnetic spectrum. They are devices in which the electronic…
Phonon Monte Carlo: Generating Random Variates for Thermal Transport Simulation
L. N. Maurer, S. Mei, I. Knezevic
Phonon Monte Carlo (PMC) is a versatile stochasic technique for solving the Boltzmann transport equation for phonons. It is particularly well suited for analyzing thermal transport…
Time-dependent transport in open systems based on quantum master equations
I. Knezevic, B. Novakovic
Electrons in the active region of a nanostructure constitute an open many-body quantum system, interacting with contacts, phonons, and photons. We review the basic premises of the…
Ballistic to diffusive crossover of heat flow in graphene ribbons
Myung-Ho Bae, Zuanyi Li, Zlatan Aksamija +5
Heat flow in nanomaterials is an important area of study, with both fundamental and technological implications. However, little is known about heat flow in two-dimensional (2D) dev…
