Popis:	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.
