References for delayed eraser experiments with electrons rather than photons?

Are there good references for delayed eraser experiments with electrons rather than photons?

As far as I know even an ordinary quantum eraser experiment hasn't been done with electrons, let alone a delayed quantum eraser experiment.

Thanks. I find this hard to believe. Any reasons why? But I am right in thinking that 'which-path' experiments have been done with electrons? Firing photons at them as they pass the slits to determine which slit they went through. And then finding the interference screen pattern replaced by a clumped pattern?

Any reasons why?

Electrons are much harder to work with than photons. They’re charged and interact readily with air molecules so can only be used in a vacuum. They can’t be reflected with mirrors, routed through fiber optic cables, or manipulated with beam splitters. Thus most experiments are done with photons unless there’s a specific reason to prefer using electrons.

However, googling for “quantum eraser electron” will bring up a few relevant results (and a bunch of false positives).

Thanks. I tried, but with spectacular lack of success. Many don't even distinguish between thought and actual physical experiments. Leave it for the moment.
