  • Radiation detectors having perovskite films
    Patent number: 12298452
    Abstract: Solid-state radiation detectors utilizing a film as an alpha detection layer are provided. The detector can include a neutron conversion layer disposed thereon to enable neutron detection. The film can detect alpha particles from the ambient environment or emitted by the neutron conversion layer (if present) so the device can detect alpha particles and/or neutrons. The film can generate electron-hole pairs and can be disposed near a semiconductor material. The film can have a thickness of, for example, at least 100 nanometers.

  • METHODS OF DEPOSITING FILMS WITH THE SAME STOICHIOMETRIC FEATURES AS THE SOURCE MATERIAL
    Publication number: 20230349068
    Abstract: Methods for depositing films using crystals or powders as a source material are provided. The films can have a thickness of at least 100 nanometers and can be inorganic (e.g., inorganic perovskite) films, and the source material can be the same composition and/or stoichiometry as the deposited film. The deposition process can be a single-step thermal process using a close space sublimation (CSS) process.
