Article Synopsis
  • - A new scintillation material featuring InAs quantum dots in a GaAs matrix was developed and tested for its efficiency with various types of radiation.
  • - The research introduced a design methodology for an integrated photodetector with low defect density, optimizing its performance to match the quantum dot emission spectrum using a specialized buffer layer.
  • - Results showed the detector's electron yield for α-particles and photons, with alpha particles yielding 13 electrons/keV and photons yielding between 30-60 electrons/keV, alongside improved radiation hardness of InAs QDs in AlGaAs compared to those in GaAs.

Traumatic brain injuries (TBIs) present with symptoms ranging from a mildly altered level of consciousness to irreversible coma and death. The most severe stage of TBIs is diffuse axonal injury and swelling affecting the whole brain. Management strategies are based on the classification of TBIs by severity and type and range from cognitive therapy sessions to complex surgeries.

Deep vein thrombosis (DVT) is a critical complication and concern in hospitalized patients due to its significant morbidity and mortality. Given the complex and multifaceted pathophysiology surrounding DVT formation, patients who have had surgical interventions faced acute or chronic trauma and prolonged immobility are at substantially high risk. Identifying these risk factors early is essential for early intervention and prophylaxis.

Epitaxial quantum dot (QD) scintillator crystals with picosecond-scale timing and high light yield have been created for medical imaging, high energy physics and national security applications. Monolithic photodetector (PD) integration enables the sensing of photons generated within the waveguiding crystal and allows a wide range of scintillator-photodetector coupling geometries. Until recently, these doubly novel devices have suffered from complex, high variance responses to monoenergetic sources which significantly reduces their precision and accuracy.
