We found something we weren't looking for, and didn't expect. It took us over a year to come to terms with what the evidence was suggesting. We said it raises questions about a violation of Kirchhoff's Law, but that's not the only way to interpret it. One way or another, if the results can be verified, some basic assumption breaks.
The tile of it is "Measuring Thermally-Driven LED Emissions via Voltage Modulation near Zero Bias" , which is something of a mouth-full. That said, the paper should be at least as accessible as our previous paper.
Here is a link to the paper.
