> We fabricated Har bar geometry sensing devices using atomically thin TaIrTe₄,

I've never heard of a "Har bar" not its geometry, but apparently neither has Google.

GPT-4o did hear of a "Hall bar geometry" though and suggested it's a typo. That one does return results on Google as well, and makes sense in context too.

Yeah, there's this line in the original paper:

> Accordingly, we measured the nonlinear Hall transport in a few-layer sample with a Hall bar device geometry at room temperature
