“…In this paper, we propose that this can be accomplished by forming a local barrier using quantum-well intermixing in a thin region immediately adjacent to the recessed trench electrodes. This approach is similar to one taken for the heterodimensional contact between the 3D metal and the 2D electron gas (2DEG) in a modulation-doped structure [8,9]. In that case, an enhanced potential barrier is formed by the electrostatic interaction between electrons in the metal and in the 2DEG.…”

circuit item that is 125 mm in length. The matching network is a three-item impedance convertor, working in the 15-30-MHz frequency. The reflection coefficient curves in complex plane ͉⌫͉ are obtained by the reflection coefficient modulus method described in this paper, and each circle ͉⌫͉ corresponds to one frequency point, with most of the values satisfying ͉⌫͉ Ͻ 0.5. CONCLUSIONIn practice, the modulus of ⌫ L is always known and the phase remains unknown. This paper has presented an in-depth study of the load-reflection coefficient modulus and its variety, as well as bandwidth inequality, and an example which achieves very good results has been given.
