Super-resolution Fluorescence Microscopy

14.9K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

NMR Spectrometers: Resolution and Error Correction

1.2K
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Atomic Force Microscopy

4.8K
Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Area of Science:

  • Surface Science
  • Condensed Matter Physics
  • Quantum Mechanics

Background:

  • Understanding electron momentum distribution is crucial for characterizing material properties.
  • Spin-resolved measurements provide deeper insights into electronic band structures and surface states.

  • To demonstrate the capabilities of the new instrument in resolving subtle electronic properties.

Main Methods:

  • Utilizing a spin-resolving momentum microscope with high energy and momentum resolution.
  • Performing measurements on a Au(111) single crystal surface.
  • Employing an imaging spin-filter based on low-energy electron diffraction (LEED) on a Au-passivated Ir(100) crystal.

Main Results:

  • Achieved an energy resolution of 12 meV and momentum resolution of 0.0049 Å⁻¹ for the Shockley surface state.
  • Observed a threefold radial symmetry in the momentum distribution, deviating from the 2D free electron gas model.
  • Successfully mapped the spin texture of the Au(111) surface state with high efficiency and reversed asymmetry.

Conclusions:

  • The developed momentum microscope offers unprecedented resolution for photoelectron momentum imaging.
  • The observed deviation from the free electron gas model highlights the complexity of surface states.
