HU Yu-guang1, LIU Jun1, WANG Yong2. Test on electromechanical coupling sensitive property of HEMT device[J]. 2012, 31(5): 145-146+152. DOI: 10.13873/j.1000-97872012.05.012.
A MEMS integrates Si micro-structure with AlGaN/GaN high-electron-mobility transistor(HEMT)devices is designed.Fabrication of the electromechanical coupling sensitive structure is achieved.The experimental test indicates that the AlGaN/GaN HEMT device has strong electromechanical coupling effect.When grid voltage is-1.5V
the value of sensitivity is up to 123.96 MPa/mA and the value of linearity is 6.95 %.
