    In this paper, we report a Spindt-type field emission array (FEA) with LaB6 as the emitting material. The LaB6 emitters were deposited by e-beam evaporation with low oxide content. As LaB6 in its vapor form is active and absorbs large quantity of residual gases, which oxidizes the LaB6 films, a...
