Commentary on the Record-Breaking Performance of Low-Dimensional Solid Photodetectors

In the last decade, papers on low-dimensional solid photodetectors have appeared in the available literature reporting the achievement of record-breaking photodetectors, better than those available on the commercial market. Several previously published papers have pointed to unrealistic claims about detector performance. The purpose of this paper is to point out the unreliable photodetector parameters noted by the author and to try to draw attention to the obvious physical limitations of photodetectors that are sometimes overlooked in estimating photodetector performance.
