Unitary Detector DPC Imaging with Multiscale Capabilities for Analysis of Local Magnetic Field of Nanomaterials
نویسندگان
چکیده
To advance with creation of novel nano-electronic devices there is a need to understand electrons behavior in a wide range of materials with dimensions reduced down to nanometer scale. It is an important task for industries dealing with magnetic memories [1], light-emitting, photovoltaic or multiferroic devices [2]. A key role for development of such devices is the nanoscale characterization of the local electro-magnetic fields in the materials [3].

Development of an MRI-compatible digital SiPM detector stack for simultaneous PET/MRI
Advances in solid-state photon detectors paved the way to combine positron emission tomography (PET) and magnetic resonance imaging (MRI) into highly integrated, truly simultaneous, hybrid imaging systems. Based on the most recent digital SiPM technology, we developed an MRI-compatible PET detector stack, intended as a building block for next generation simultaneous PET/MRI systems. Our detecto...
متن کاملNumerical Procedures to determine Potential Distribution from Electronic Field Vectors observed in Differential Phase Contrast (DPC) imaging
Recently, the differential phase contrast (DPC) imaging in STEM becomes a hot topic, since then the possibility of the DPC imaging at atomic resolution has been demonstrated [1]. The idea of the DPC imaging in STEM was proposed by Dekker and de Lang [2] and mainly used for a study of magnetic material in a medium resolution [3]. Müler et al. showed that the expectation value of the momentum tra...
متن کاملDynamics of Macro–Nano Mechanical Systems; Fixed Interfacial Multiscale Method
The continuum based approaches don’t provide the correct physics in atomic scales. On the other hand, the molecular based approaches are limited by the length and simulated process time. As an attractive alternative, this paper proposes the Fixed Interfacial Multiscale Method (FIMM) for computationally and mathematically efficient modeling of solid structures. The approach is applicable to mult...

Introduction Range and diffusion of positron-emitting radiopharmaceuticals are important parameters for image resolution in positron emission tomography (PET). In this study, GEANT4 toolkit was applied to study positron diffusion in soft tissues with and without a magnetic field for six commonly used isotopes in PET imaging including 11C, 13N, 15O, 18F, 68Ga, and 82Rb. Materials and Methods GEA...
