High-quality quaternary ZnSTeSe epitaxial layers were successfully grown by molecular beam epitaxy (MBE). It was found that a ZnS0.18Se0.82 layer was automatically formed in between the ZnSe buffer layer, and the ZnS0.17Te0.08Se0.75 epitaxial layer, when we increased the ZnS cell temperature. ZnSTeSe metal-semiconductor-metal (MSM) photodetectors were also fabricated for the first time. It was found that we could achieve a photo current to dark current contrast higher than five orders of magnitude by applying a 10-V reverse bias. We also found that the maximum photo responsivity is about 0.4 A/W under a 10-V reverse bias. Such a value suggests that the ZnSTeSe MSM photodetector is potentially useful in the blue-UV spectral region.
