Effect of Spectral Diffusion on the Coherence Properties of a Single Quantum Emitter in Hexagonal Boron Nitride

Autor: Moungi G. Bawendi, Dirk Englund, Hendrik Utzat, Boris Spokoyny, Hyowon Moon, Gabriele Grosso

Publikováno v: The Journal of Physical Chemistry Letters. 11:1330-1335

Quantum emitters capable of producing single photons on-demand with high color purity are the building blocks of emerging schemes in secure quantum communications, quantum computing, and quantum metrology. Such solid-state systems, however, are usual

Blue Light Emitting Defective Nanocrystals Composed of Earth‐Abundant Elements

Autor: Eric C. Hansen, Yun Liu, Hendrik Utzat, Sophie N. Bertram, Jeffrey C. Grossman, Moungi G. Bawendi

Publikováno v: Angewandte Chemie International Edition. 59:860-867

Copper-based ternary (I-III-VI) chalcogenide nanocrystals (NCs) are compositionally-flexible semiconductors that do not contain lead (Pb) or cadmium (Cd). Cu-In-S NCs are the dominantly studied member of this important materials class and have been r

Lifetime-resolved photon-correlation Fourier spectroscopy

Autor: Hendrik Utzat, Moungi G. Bawendi

Publikováno v: Optics express. 29(10)

The excited state population of single solid-state emitters is subjected to energy fluctuations around the equilibrium driven by the bath and relaxation through the emission of phonons or photons. Simultaneous measurement of the associated spectral d
