Propulsion Engineering Lab
Machine-translated · View original
The lab examines, at the atomic level, what happens at the surfaces where plasma meets materials.
AboutAbout the lab
The power of plasma, from space to the nanoscale.
The Propulsion Engineering Lab conducts basic and applied research on plasma (ionized gas) and reactive gases related to the propulsion of aerospace vehicles.
Along with their dynamical properties, the lab focuses on the reactions of atoms, molecules, and ions in gases and their interactions with solid surfaces.
Centered on experiments and also using numerical simulation, the lab tackles challenges in advanced technologies such as semiconductors, in addition to aerospace engineering.
Key terms
- Plasma
- A state in which the atoms and molecules of a gas are separated into electrons and ions, with charged particles moving around freely
- Insulating film
- A thin film that does not conduct electricity. It is used in semiconductor devices to separate electrical parts
- Resistive random-access memory
- Memory that records information by applying voltage to switch between high and low electrical resistance
ResearchResearch themes
The lab seeks to understand the mechanisms of nanoscale reactions at the surfaces and interfaces of solids in contact with plasma. It explores engineering applications of plasma and the design of materials and devices with high functionality and reliability in extreme environments.
*Illustrative imageSurface Reactions in Extreme Environments
Nanoscale interactions between plasma and the surfaces of insulating films, semiconductors, and metals also affect the lifetime of entire systems. The lab aims to understand these reactions at the atomic level and to predict and control phenomena such as material corrosion in extreme environments.
*Illustrative imageMaterials and Devices That Survive in Space
The lab designs materials and devices that achieve high performance and high reliability in extreme environments such as outer space. Its work includes thin films of boron nitride, which is highly plasma-resistant and extremely hard, and the design of radiation-resistant resistive random-access memory.
*Illustrative imageNew Ways to Measure Material Properties
Toward the design of highly reliable materials, the lab develops new analysis and design methods that focus on the dielectric function and quantum tunneling processes. This includes new spectroscopy methods for the nanoscale.
*Illustrative imageCreating, Measuring, and Using Plasma
Through measurement experiments, the lab studies how electrons, ions, and excited particles are generated in plasma. It also studies new ways of generating plasma, interactions with surfaces in nanofabrication and thin-film deposition, and optical and electrical measurement methods.
