    • A polycrystalline film is prepared by (a) providing a substrate having a thin film disposed thereon, said film capable of laser-induced melting, (b) generating a sequence of laser pulses having a fluence that is sufficient to melt the film throughout its thickness in an irradiated region, each pulse forming a line beam having a predetermined length and width, said width sufficient to prevent nucleation of solids in a portion of the thin film that is irradiated by the laser pulse, (c) irradiating a first region of the film with a first laser pulse to form a first molten zone, said first molten zone demonstrating a variation in width along its length to thereby define a maximum width (Wmax) and a minimum width (WmJn), wherein the first molten zone crystallizes upon cooling to form one or more laterally grown crystals, (d) laterally moving the film in the direction of lateral growth a distance that is greater than about one-half Wmax and less than Wmjn; and (e) irradiating a second region of the film with a second laser pulse to form a second molten zone having a shape that is substantially the same as the shape of the first molten zone, wherein the second molten zone crystallizes upon cooling to form one or more laterally grown crystals that are elongations of the one or more crystals in the first region.
    • 通过(a)提供具有设置在其上的薄膜的基板,所述膜能够进行激光诱导熔化,(b)产生具有足以使膜在整个厚度上熔化的能量密度的激光脉冲序列来制备多晶膜 在照射区域中,每个脉冲形成具有预定长度和宽度的线束,所述宽度足以防止由激光脉冲照射的薄膜部分中的固体成核,(c)照射第一区域 膜,其具有第一激光脉冲以形成第一熔融区,所述第一熔融区表现出沿其长度的宽度变化,从而限定最大宽度(Wmax)和最小宽度(WmJn),其中第一熔融区在冷却时结晶 以形成一个或多个横向生长的晶体,(d)沿横向生长方向横向移动所述膜的距离大于约一半Wmax且小于Wmjn; 和(e)用第二激光脉冲照射所述膜的第二区域以形成具有与所述第一熔融区域的形状基本相同的形状的第二熔融区域,其中所述第二熔融区域在冷却时结晶以形成一个 或更多横向生长的晶体,其是第一区域中的一种或多种晶体的伸长率。
