Surface Improvement of InAlAs/InGaAs InP-Based HEMT Through Treatments of UV/Ozone and TMAH

In this paper, we introduce novel surface treatments of UV/Ozone and TMAH to solve the surface problem of gate recess of InAlAs/InGaAs InP-based HEMTs. The problem of nonstoichiometric surface of InP etch stopper layer was found to be the result of donor-like surface defects brought by HF damage, br...
