An Andreev billiard was realised in an array of niobium filled antidots in a high-mobility InAs/AlGaSb heterostructure. Below the critical temperature T_C of the Nb dots we observe a strong reduction of the resistance around B=0 and a suppression of the commensurability peaks which are usually found in antidot lattices. Both effects can be explained in a classical Kubo approach by considering the ...
