    摘要: A compound semiconductor multilayer structure is formed on a Si substrate. The compound semiconductor multilayer structure includes an electrode transit layer, an electrode donor layer formed above the electron transit layer, and a cap layer formed above the electron donor layer. The cap layer contains a first crystal polarized in the same direction as the electron transit layer and the electron donor layer and a second crystal polarized in the direction opposite to the polarization direction of the electron transit layer and the electron donor layer.
