    Applied Carbon Nanotechnology Lab energy micro-supercapacitors quantum dots

    Micro-supercapacitors (MCs) are miniaturized energy storage devices that can enhance the performance of wearable health devices, medical implants, wireless sensors, and micro-electromechanical systems due to their fast frequency response, long life cycle, and vast temperature operation. However, to make these MC systems into commercially feasible products, necessary improvements to current MC performance are necessary, primarily in increasing the energy density. Reducing the electrode materials’ dimension is the most effective approach to boost the performance of MCs. Graphene quantum dots (QDs) have already shown improved response over conventional MCs. This work aims to develop QDs from MXene, a class of layered transition metal carbides, carbonitrides or nitrides. These MXene QDs will increase the energy density of MCs by twofold and optimize their electrochemical performance for commercial viability. MXene of an optimized size for QDs will be produced using environmentally friendly etching methods. MXene QDs with different terminations will then be prepared and used as electrodes to fabricate MCs and to evaluate the capacitance and stability. Density Functional Theory (DFT) methods will be used to examine the physical properties of the materials and further understand the experimental results. The MCs that display the best performance will be assembled to study their characteristics further. The research will provide a green synthesis protocol of MXene and accelerate the discovery of optimized MXene QD materials. Moreover, the MXene QD MC devices will have increased energy storage performance and durability, ideally suited for the next generation of wearable health devices and clean energy storage.

    Topological Properties of Exciton-Polaritons in a Kagome Lattice as a Solid-state Quantum Simulator

    Summary   In this project, we build a solid-state quantum simulator for engineering a specific Hamiltonian. Quantum simulators are purpose-built devices with little to no need for error correction, thereby making this type of hardware less demanding than universal quantum computers. Our platform consists of exciton-polariton condensates in multiple quantum-wells sandwiched in a semiconductor Bragg […]

    Entangled States of Beams and their Applications

    Summary   With David Cory and collaborators at the National Institute of Standards and Technology (NIST) we explore how to engineer beams of neutron or photons that carry entanglement. The degrees of freedom that can be entangled include spin (polarization), momentum, displacement, and angular momentum. These have potential applications ranging from studies of helical internal magnetic fields […]

    Quantum Sensing with Small Quantum Systems

    Summary   There are small quantum systems over which we have very good control and which have long lifetimes. Examples include the phosphorous (P) defect in silicon (Si) and the nitrogen vacancy (NV) defect in diamond. With P defect in Si, we focus on improving our understanding of the hyperpolarization mechanism to better enable engineering of […]

    A Reformulation of Quantum Game Theory

    Summary Classical game theory – conducted at the interface between economics and computer science – has found applications in topics ranging from networking and security to online markets. Despite over 20 years of research into connections between game theory and quantum information, we have yet to see any significant implications of quantum information when applied […]
