根据物理参数研究肖特基势垒探测器的性能特征。结果表明，通过正确选择探测器参数，可以最大化探测器截止频率和响应度带宽积，同时可以最小化最小可探测功率水平。对于零偏压探测器，最佳势垒高度在 0.2 至 0.4 eV 之间。对于更高的势垒高度，可以通过正向偏置探测器来获得优化的性能。
Performance characteristics of Schottky-barrier detectors are investigated in terms of their physical parameters. It is shown that the detector cut-off frequency and responsivity-bandwidth product can be maximised while the level of minimum detectable power can be minimised by the proper choice of detector parameters. For zero-bias detectors, the optimum barrier heights are found to range between 0.2 and 0.4 eV. For higher barrier heights, the optimised performance can be obtained by forward-biasing the detector.
