We have grown GaN on nearly lattice matched ZrB_2 substrates at low substrate temperatures by the use of PLD. We have found that high quality GaN grows on ZrB_2 substrates with the layer-by-layer mode even at room temperature. This success can be attributed to the suppression of interfacial reaction between GaN and ZrB_2.
