Abstract Entstehung und Wachstum der Whisker durch Überleiten von nassem Wasserstoff über GaP bzw. Ga-Ausgangsmaterial bei 1100°C. Wachstumsunterbrechung durch Ga-Tröpfchen an den Whiskerspitzen, Bildung von Verwachsungen und Verzweigungen, Strecken geknickter oder gekrümmter Whisker. Zeitraffung.
The film shows the growth of GaP whiskers which are obtained in the temperature range of 900 to 1050° C when wet hydrogen is passed ove GaP and Ga materials of about 1100° C. One can see in detail the termination of whisker growth when Ga droplets appear on the whisker tips, the encapsulation of a Ga droplet by a GaP layer, the approach, fusion and common growth of two intersecting whiskers, the branching of whiskers, and the straightening of initially bent or kinked whiskers.
