Abstract：

Due　to　the　strong　light–matter　interactions,　van　der　Waals　semiconducting　materials　have　shown　their　great　potential　in　the　development　of　high-performance　photodetectors.　However,　the　van　der　Waals　semiconducting　devices　via　conventional　growth　method　often　introduce　defects　or　are　in　the　form　of　isolated　flakes,　which　hinders　the　optoelectronics　from　widespread　applications.　In　this　paper,　van　der　Waals　semiconductor　indium　selenide　(InSe)　fibers　for　photodetection　were　developed　based　on　thermal　drawing.　Meters　level　length　of　InSe　fibers　have　been　fabricated　through　thermal　drawing,　and　the　problem　of　easy　cracking　of　InSe　is　solved.　The　InSe　fibers　have　high　crystallinity,　and　it　is　found　that　the　cleavage　planes　have　a　preferential　orientation.　The　InSe　fibers　show　a　high-speed　response　to　modulated　639　nm　laser　irradiation　with　up　to　10　kHz　repetition　rate.　In　addition,　the　photoelectric　response　of　the　fibers　were　further　improved　through　annealing　by　CO2　laser.　©　2022　SPIE.
