Abstract: 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.

Abstract: The present disclosure generally relates to field emission cathode structure for a field emission arrangement, specifically adapted for enhance reliability and prolong the lifetime of the field emission arrangement by arranging a getter element underneath a gas permeable portion of the field emission cathode structure. The present disclosure also relates to a field emission lighting arrangement comprising such a field emission cathode structure and to a field emission lighting system.
