Majorana neutrinos would generate neutrinoless double-$\\beta$ ($0\\nu\\beta\\beta$) decay, a matter-creating process without the balancing emission of antimatter. So far, 0$\\nu\\beta\\beta$ decay has eluded detection. The GERDA collaboration searches for the $0\\nu\\beta\\beta$ decay of $^{76}$Ge by operating bare germanium detectors in an active liquid argon shield.
