Summary
Researchers developed a new nanometer-scale nuclear quadrupole resonance (NQR) spectroscopy technique. This method uses diamond impurities to probe 2D materials like hexagonal boron nitride (h-BN) at the atomic level.
Area of Science:
- Condensed Matter Physics
- Quantum Information Science
- Materials Science
Background:
- Two-dimensional (2D) materials are crucial for novel phenomena and technologies.
- Probing atomic-scale materials is challenging for traditional macroscopic techniques.
- Existing methods struggle to interface with the reduced dimensionality of 2D materials.
Purpose of the Study:
- To demonstrate a novel method for probing 2D material properties at the nanoscale.
- To overcome limitations of traditional measurement techniques for atomic-scale materials.
- To enable the characterization of low-dimensional nanoscale materials.
Main Methods:
- Utilized nanometer-scale nuclear quadrupole resonance (NQR) spectroscopy.
- Employed individual atomlike impurities in diamond as probes.
- Leveraged coherent manipulation of nitrogen-vacancy (NV) color centers in diamond.
Main Results:
- Successfully probed nanoscale ensembles of atomically thin hexagonal boron nitride (h-BN).
- Achieved sensitivity down to approximately 30 nuclear spins.
- Demonstrated a viable technique for nanoscale characterization of 2D materials.
Conclusions:

1.3K
The number of nuclear spins aligned in the lower energy state is slightly greater than those in the higher energy state. In the presence of an external magnetic field, as the spins precess at the Larmor frequency, the excess population results in a net magnetization oriented along the z axis. When a pulse or a short burst of radio waves at the Larmor frequency is applied along the x axis, the coupling of frequencies causes resonance and flips the nuclear spins of the excess population from the...

2.1K
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of one, the...

3.5K
The spin state of an NMR-active nucleus can have a slight effect on its immediate electronic environment. This effect propagates through the intervening bonds and affects the electronic environments of NMR-active nuclei up to three bonds away; occasionally, even farther. This phenomenon is called spin–spin coupling or J-coupling. Coupling interactions are mutual and result in small changes in the absorption frequencies of both nuclei involved. While nuclei of the same element are involved...

Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.

01:23Atomic Nuclei: Nuclear Relaxation Processes
1.3K
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis.

All atomic particles possess an intrinsic angular momentum, or 'spin'. Electrons, protons, and neutrons each have a spin value of ½, although protons and neutrons in nuclei may have higher half-integer spins owing to energetic factors.
Atomic nuclei have a net nuclear spin, , which can have an integer or half-integer value. In atomic nuclei, the spins of protons are paired against each other but not with neutrons, and vice versa. Consequently, an even number of protons does not contribute to...
