Silicon-based reconfigurable antenna,which is fabricated by heterogeneous and lateral surface PiN(SPiN),is an effective technology to achieve antenna miniaturization and enhance radar and wireless communication system performance.In this paper,the heterogeneous and lateral Si/Ge/SiSPiN diode is presented,that can weaken the band gap narrowing of the P~+ and N~+ region to improve the injection ratio of PN junction.And the electrical properties of the solid state plasma within the intrinsic region are also st...
