摘要： The present invention relates to a method for controllably growing ZnO nanowires, for example to be used in relation to field emission lighting. In particular, the invention relates to a method of controlling thermal oxidation conditions to achieve steady-state conditions between an oxygen consumption rate by a growing oxide on a surface of a structure and the decomposition rate of the oxygen-carrying species within the chamber. The invention also relates to a corresponding field emission cathode.
