A method and apparatus for producing crystalline ribbons by zone melting. Means for coupling electromagnetic energy into a film of material are provided to appropriately induce electrical currents in order to control and restrict the molten zone and suppress net loss of the heat of fusion from the balance of the ribbon in contact with the melt, thus controlling the thickness uniformity of the resulting ribbon. The heat of crystallization is selectively removed by a heat absorbing means from one end of the melt zone in a direction substantially perpendicular to the direction of pulling.
