Abstract:This study investigates the influence of surface nitridation
of
Ta metal foil substrates on the growth of GaN nanorods using the laser
molecular beam epitaxy (LMBE) technique and the field emission characteristics
of the grown GaN nanorod ensemble. Surface morphology examinations
underscore the pivotal role of Ta foil nitridation in shaping the
dimensions and densities of GaN nanorods. Bare Ta foil fosters the
formation of high-density, vertically self-aligned GaN nanorods at
a growth temperature of 700 °C. Fu… Show more
