论文摘要
电气3 dB带宽通常用作光电探测器响应速度的度量，并通过文献中的各种方法估算，从直接测量到通过近似值进行测量值。在比较这3个dB带宽时，必须格外小心，因为近似值仅对理想电路严格有效。本文表明，对于基于新的新兴纳米结构材料（即量子点和过渡金属二核苷）的典型光电探测器，带宽最高可偏离10^3，这取决于带宽规范的选择方法。
The electrical 3 dB bandwidth is regularly used as a measure for the response speed of a photodetector and is estimated via various approaches in literature, ranging from direct measurements to gauged values via approximations. Great care must be taken when comparing these 3 dB bandwidths, since approximations are only strictly valid for ideal circuits. This paper demonstrates that, for typical photodetectors based on new emerging nanostructured materials, namely quantum dots and transition metal dichalcogenides, the bandwidth can deviate up to 10^3 depending on the chosen approach for the bandwidth specification.
