DESCRIPTION:Prof. Christina Scheu\, Ludwig-Maximilians-Universität Mün
 chen\, Germany\nUltrathin non-conducting nanowires are promising candidate
 s for application in nanoelectronics  and in drug-delivery systems. Ee ha
 ve studied the self-catalytic vapor-liquid-solid (VLS) growth of alumina n
 anowires in-situ at 750 degrees Celsius in a high voltage transmission ele
 ctron microscope [1]. The atomic scale observation revealed that the growt
 h of the nanowire in [0001] direction takes place layer-by-layer involving
  a two-step mechanism. Oscillatory growth and dissolution reactions altern
 ate at the top rim of the nanowire which is in contact to the liquid Al dr
 oplet and the vapor phase leading to periodical changes of the triple junc
 tion configuration. The dissolution reaction of the crystalline top rim su
 pplies the oxygen which is required to grow a new (0006) alumina layer [1]
 . The growth of the (0006) layer is relatively fast since the Al atoms in 
 the liquid adjacent to the crystalline alumina wire possess already simila
 r position as in the solid [2]. This leads to an easy pathway for the inte
 rfacial diffusion of oxygen. The rate limiting step for growth of the alum
 ina nanowire is the oxygen transport after completion of a new (0006) alum
 ina layer when the crystalline rim is formed.\n[1] Oh\, Chisholm\, Kauffma
