EERE Silicon Electrolyte Interface Stabilization (SIESta) FY19 Q2 Report
- Univ. of Colorado, Boulder, CO (United States)
- Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)
This quarter, we have focused on characterizing the electrochemical of native oxide and "pristine' silicon surfaces by electrochemical cycling for various conditions, starting with either a freshly etched Si surface, or varying amounts of oxide on the surface (either native grown or deposited). These changes can be used to determine if the pristine surface evolves differently than those that have been modified (Q1 milestone). We are also developing new diagnostics (microcalorimetry and stress measurement in-situ) to determine how the nature of the silicon surface affects the composition, function, and thickness of the SEI (Q2 milestone).
