Nanometer-sized gold tips were used to create bright single photon emitters in transition metal dichalcogenides (TMDs) with ultrahigh spatial precisions.
Significance and Impact
This work will enable the creation of bright, large scale single photon sources in TMDs that could be used for quantum communication applications.
- We fabricated TMD monolayers and induced local strain fields with high spatial previsions by using nanometer-sized gold tips.
- We studied the single photon emission qualities of the emitters using low-temperature single particle spectroscopy.
- The study employed the photon-correlation microscope at the Center for Nanoscale Materials (CNM).
Work was performed in part at CNM.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials is one of the five DOE Nanoscale Science Research Centers, premier national user facilities for interdisciplinary research at the nanoscale supported by the DOE Office of Science. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, Sandia and Los Alamos National Laboratories.
