An interesting InGaP/InGaAs quantum-well delta-doped-channel field-effect transistor is fabricated and demonstrated. Due to the employed InGaAs dual quantum-well delta-doped-channel structure and Schottky behaviors of InGaP "insulator", good DC properties including higher turn-on voltage, lower leakage current, better linearity, and good RF performances are obtained. In addition, the experimental results are fitted well with theoretical simulation data based on a two-dimensional simulator. Moreover, the studied device exhibits relatively negligible temperature-dependent characteristics over wide operating temperature region (300<T<450K). Therefore, the studied device provides the promise for high-temperature and high-performance microwave electronic applications.
