Research Interests

Materials Integration of Semiconductors, Metals, and Optical Materials; High resolution X-ray scattering: Electron Microscopy and Spectroscopy; Ion Implantation; Wide Bandgap Semiconductors; Electrical and Thermal Transport Engineering at Interfaces; Chemical-Mechanical Polishing.

  • Our research projects focus on the relationship between structural and chemical irregularities in solid state electronic materials and the effect that these defects have on the performance of devices fabricated from these materials. Our research often involves collaboration with industrial and government laboratories to provide a synergistic effort to study these issues. In particular, we use non-destructive techniques to study the behavior of defects in these structures.
  • Our primary efforts in materials integration include:
    • i) Electrical transport across III-V bonded heterojunctions. We have pioneered techniques to produce low resistance interfaces and this approach has been utilized by other to produce world-record solar cell efficiencies.
    • ii) Thermocompression bonding of Cu-Cu and Au-Au terminated later structures through fundamental studies of the roles of surface morphology, compressive force, temperature, and phase transformations. This approach enables Heterogeneous Integration and Performance Scaling by integrating small dielets onto an engineered substrate at pitches comparable to on-chip wiring levels.
    • iii) Thermal transport across dissimilar materials such as diamond-GaN interfaces and engineering these interfaces to reduce thermal barrier resistance through analysis of the nano-scale chemical and structural properties of the interfaces.
  • Wide bandgap materials can be used to produce devices that outperform commercial devices by operating at higher voltages, temperatures and frequencies. These devices will have significant impact in the areas consumer electronics, the electricity grid, power supplies, solar and wind power, automotive, ship propulsion, and aerospace. We are addressing ion implantation for selective dopant activation, epitaxial regrowth, and bonding GaN to other materials to provide a path to high performance.
  • Porous semiconductors represent an underutilized class of materials – we are exploiting porous semiconductors in the areas of epitaxial liftoff and layer transfer and targeted drug delivery vehicles for medical applications.
  • Advanced characterization techniques are utilized in collaborations to produce unique and high performance materials structures for solar cells and flexible substrates.
