The curious properties of gallium and related liquid metals, “especially the tendency to spontaneously form thin oxide skins in air,” have led researchers in recent years to use these materials for chemical patterning and for making stretchy and self-healing electronics. Now, a team of researchers in Australia and the U.S. has exploited that property to prepare these materials as large, ultrathin patterned semiconductor films via methods that are compatible with . . .
