==Short Description==
 
he goal of this project is to determine the relevant Redox processes taking place at metal/oxide interfaces and derive the parameters describing them. For this purpose, the electronic structure of exemplary systems represinting the  different  reaction  stages  (e.g. metallic  atom  in  bulk  metal,  metal  ion  at  the  metal/oxide  interface,  metal  ion dissolved in the oxide) will be calculated. These simulations will be conducted on our in-house HPC clusters using density functional theory (DFT). From the obtained data sets, the student will derive the essential parameters by using post-processing and analysis scripts. If time allows (Master’s thesis), the developed work flow will be applied to a large number of different metal/oxide pairs so that their applicability in CBRAM applications can be validated.

Conductive bridging RAM (CBRAM)is an emerging (non-)volatile memory storage technolgy. Its operation principle relies on the repeatable formationand disruption of a metallic filament bridging an oxide layer sandwiched between two electrodes. The electrochemical properties ofthe metal/oxide interface play a crucial roleby determining the rates of the Redox reactions.The latter strongly influences the growth,dissolutionand stabilityof the filament.The Nano-TCAD group has developed an electrochemical model in COMSOL to simulate ON/OFF switching in CBRAM. So far, the model still depends on a number of free input parameters, among them critical onessuch as the Redox parameters of the involved chemical species. Therefore, we aim at replacingthese by values derived from DFT. Eventually, this refined model should not only help us to understand and confirm results obtained from experimental measurements, but could also be used to predict the behaviour of new, not-yet-fabricated devices.

The Big Picture

LSPR AG, a Swiss deep tech startup company, develops the 4th generation DNA single molecule, plasmonic DNA sequencing technology with the objective of providing easily accessible, complete and affordable personal genetic information for every individual on the planet. .

Status: Available

Interested candidates please contact: Benedikt Oswald

Prerequisites

We are looking for students who will contribute to change the world of DNA sequencing technology forever. This project is not for the faint at heart. We operate in a highly competitive, globally distributed field. In particular, we are looking for one or several students who will contribute to detailed theoretical understanding of single molecule, plasmonic DNA sequencing on the basis of leading edge, fully-coupled, self-consistent quantum-electrodynamics (QED) calculations. Expansion into clean room based nanofabrication work is also possible, given sufficient time.
