Individual CdS nanobelts are assembled for high-performance visible-light photodetectors with an ultrafast response time of ∼20 μs and ultrahigh quantum efficiency of 1.9 × 107%. The results suggest a high potential of utilizing these CdS nanobelts as optoelectronic nanodevices. References 1 a) C. M. Lieber, Z. L. Wang, MRS Bull 2007, 32, 99. b) Y. N. Xia, P. D. Yang, Y. G.
