Determination of Crystal Structures

131
In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...

Area of Science:

  • Materials Science
  • Nuclear Instrumentation
  • Medical Imaging Physics

Background:

  • Coplanar grid (CPG) cadmium zinc telluride (CdZnTe) detectors are established gamma-ray spectrometers.
  • CPG CdZnTe detectors traditionally exhibit poor spatial resolution, limiting their use in imaging.
  • Pixelated CdZnTe detectors offer better spatial resolution but CPG designs are simpler.

Purpose of the Study:

  • To enhance the spatial resolution of CPG CdZnTe detectors for imaging applications.
  • To maintain good energy resolution while improving spatial performance.
  • To demonstrate the feasibility of CPG CdZnTe detectors in high-resolution imaging.

Main Methods:

  • Fabrication of a 2x2 CPG array CdZnTe detector (7x7x5mm³).
  • Moderate shrinking and precise design of CPG pairs to mitigate surface charge loss.
  • Evaluation of energy and spatial resolution using 662keV gamma rays.

Main Results:

  • Achieved an energy resolution of 2.7-3.9% for the four CPG pairs.
  • Demonstrated a spatial resolution of 3.3mm, the best reported for CPG CdZnTe detectors.
  • Confirmed the potential for improved imaging capabilities.

Conclusions:

  • The modified CPG CdZnTe detector design significantly enhances spatial resolution.
  • This advancement allows CPG CdZnTe detectors to be viable for imaging applications.
  • The study presents a new benchmark for CPG CdZnTe detector spatial performance.
