The storage capacity is an important property which can enhance the battery life of today's portable devices, like smartphones and notebooks, as well as of electric vehicles. Therefore, we are investigating different electrode materials for Li-ion batteries with the help of advanced simulation tools for nanoscale devices. Tin (Sn), for example, provides a storage capacity for lithium which is more than twice as much as the capacity of the widely used anode material graphite. An analysis of the electron conductance is necessary to ensure that the material characteristics do not limit the charge/discharge process of the battery.

Short Description

In this project, the student will develop a quantum-transport based hybrid plasmonic laser simulator by extending our in-house quantum-transport solver with electron-photon coupling. The functionality of the implemented solver should be validated by simulating laser devices fabricated at IBM and reproducing the experimental data.

The Big Picture

The exploding data growth nowadays requires photonic ICs with low-power consumption. However, scaling down optoelectronic devices to sub-wavelength range is physically impossible due to the diffraction limit of light. But this limit can be broken by using plasmonics. By coupling photons to collective motion of electrons in metals, surface plasmon polaritons (SPPs) are formed at a metal/dielectric interface. This enables strong confinement of photons to nanometer scale.

Type of Work

Theory & Simulation

Prerequisites

We are seeking a candidate with a strong interest in sub-wavelength optoelectronics as well as basic knowledge in quantum mechanics, optics and numerical simulation. Knowledge with plasmonics is a plus but not required.
