Micron-gap spacers with ultrahigh thermal resistance and mechanical robustness for direct energy conversion
In thermionic energy converters, the absolute efficiency can be increased up to 40% if space-charge losses are eliminated by using a sub-10-µm gap between the electrodes. One practical way to achieve such small gaps over large device areas is to use a stiff and thermally insulating spacer between th...
