The four key thrusts of research are: (a) renewable energy materials (b) heterogeneous integration and advanced semiconductor packaging (c) in-situ and in-operando testing and characterization (d) materials sustainability. A few example projects are included in each research thrust.
Renewable Energy
- Metastability and long-term degradation of halide perovskite and chalcogenide thin-film PV.
- Stable and low-temperature processable wide bandgap p-type semiconductors for bifacial solar cells.
- Development of stable and sustainable Pb-free halide and chalcogenide perovskites for PV and PEC applications.
Semiconductor Packaging:
- High lifetime electrical contacts for 2D semiconductors for BEOL integration.
- Electro-thermo-mechanical reliability of embedded contacts and interconnects.
- Novel materials and package architectures for electro-thermo-mechanical reliability of high temperature sensors and electronics.
- Reliable and fine pitch on-chip and off-chip interconnects.
- Reliability of thermal interface materials in immersion cooling systems.
- Reliability of Pb-free high temperature solders.
Application of in-situ and in-operando characterization methods to identify degradation modes and understand the underlying degradation mechanisms.
- Metastability and degradation in thin-film PV.
- In-situ creep and fatigue characterization in thin-film MEMS structures.
Materials Sustainability:
- Recovery of critical metals/non-metals/semiconductors through sustainable extraction methods.
- Sustainable and zero-waste additive methods to process devices and semiconductor packages.
