Abstract
Bulk samples of the layered ternary nitride Cr2GaN were observed to extrude filaments of pure elemental gallium at room temperature. This self-extrusi on phenomenon is best described as a room-temperature deintercalation of ga llium from the basal planes of porous Cr2GaN samples. The extruded filament s are single crystals with 2- to 100-micrometer diameters and can be severa l centimeters long.
