Student: Stephen Hodson Faculty: Tim Fisher Sponsor: Raytheon Integrated Systems / DARPA Challenges - Strengthen thermal connection between two surfaces
- Mitigate weak bonding at heterogenous interfaces
- Address differences in phonon dispersion & density of states
- Combat wave constriction affects at nanoscale contacts
- Maintain performance under thermal cycling and stability conditions
- Accurately characterize the CNT array (density, diameter distribution, and height)
Approach - Growth of vertically aligned multi-walled CNT arrays on various substrates
- Development of bonding techniques that include post-growth functionalization and coating
- Assess thermal performance by photoacoustic and ns-thermoreflectance techniques
- Model statistical nature of CNT array characteristics (density and height)
