摘要: A method for determining the structure of a transistor having at least one first layer including GaN, one second layer including AlxGa1-xN disposed on the first layer, and one fourth layer including a metal or an alloy disposed on the second layer. The method includes setting the layer thickness of the second layer, setting the aluminum content x of the second layer, producing at least the second layer and the first layer, determining the surface potential of formula (I) and/or the charge carrier density n, and/or the charge carrier motility μ after producing the second layer and the first layer, and selecting the material of the fourth layer as a function of the at least one measurement result.
