Superballistic electron flow through a point contact in a Ga[Al]As heterostructure

We measure electronic transport through point contacts in a high-mobility electron gas in a Ga[Al]As heterostructure at different temperatures and bulk electron densities. The conductance through all point contacts increases with increasing temperature in a temperature window around T∼10K for all in...
