Hybridization of Atomic Orbitals I

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

The Aufbau Principle and Hund's Rule

65.0K
To determine the electron configuration for any particular atom, we can build the structures in the order of atomic numbers. Beginning with hydrogen, and continuing across the periods of the periodic table, we add one proton at a time to the nucleus and one electron to the proper subshell until we have described the electron configurations of all the elements. This procedure is called the aufbau principle, from the German word aufbau (“to build up”). Each added electron occupies the...

Area of Science:

  • Solid-state physics
  • Quantum optics
  • Materials science

Background:

  • Quantum emitters are crucial for quantum sensing and computing.
  • Hexagonal boron nitride (hBN) is a promising solid-state platform for quantum emitters due to its brightness, stability, and spin-photon interface potential.
  • The physical origins of single-photon emitters (SPEs) in hBN remain largely uncharacterized.

Purpose of the Study:

  • To investigate the physical origins of single-photon emitters (SPEs) in hexagonal boron nitride (hBN).
  • To demonstrate dense SPEs across the visible spectrum in hBN.
  • To establish a theoretical model explaining the observed emission spectra.

Main Methods:

  • Experimental photoluminescence spectroscopy to identify and characterize SPEs in hBN.
  • Theoretical modeling based on donor-acceptor pair (DAP) transition mechanisms.
  • Comparison of calculated wavelength fingerprints with experimental spectra.

Main Results:

  • Dense single-photon emitters (SPEs) were observed in hBN across the entire visible spectrum.
  • Evidence suggests that donor-acceptor pairs (DAPs) are the dominant mechanism for most observed SPEs.
  • Calculated DAP transition wavelengths closely matched the experimental photoluminescence spectrum.

Conclusions:

  • Donor-acceptor pairs (DAPs) provide a strong explanation for the physical origin of SPEs in hBN.
  • This understanding is a significant step towards the reliable application of hBN in quantum technologies.
  • The findings facilitate the development of advanced quantum sensing and computing devices.
