The Geometry of a Quantum Circuit and its Impact on Electromagnetic Noise [PDF]

open access: yesarXiv, 2018
Here we show that to quantize any lumped element circuit, the circuit geometry must be included in a mathematical model of either the circuit fluxes or the circuit charges. By geometry of the circuit, we refer to the so-called parasitic inductances and capacitances that arise from the details of the circuit layout, which are well known to create noise ...

Double Helical Plasmonic Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

open access: yesAdvanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Integrated Pristine van der Waals Homojunctions for Self‐Powered Image Sensors

open access: yesAdvanced Materials, EarlyView.
Pristine van der Waals homojunctions consisting of 2H‐MoTe2 layers with asymmetric thickness are constructed to eliminate heterogenous interfaces and obtain clean boundaries. The layer‐engineered energy bands of 2H‐MoTe2 layers induce a built‐in electric field at the interface, enabling self‐powered photodetection. Furthermore, a 10 × 10 array based on

Electromagnetic-Field-Based Circuit Theory and Charge-Flux-Flow Diagrams [PDF]

open access: yesarXiv
The conventional circuit diagrams and graph-based circuit theory are used for the phase-independent circuits such as resistor-inductor-capacitor (RLC) circuits and semiconductor transistor circuits, rather than for the phase-dependent circuits such as Josephson junction circuits and quantum-phase-slip (QPS) junction circuits.

Optoelectronic Devices for In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
The raw data obtained directly from sensors in the noisy analogue domain is often unstructured, which lacks a predefined format or organization and does not conform to a specific data model. Optoelectronic devices for in‐sensor visual processing can integrate perception, memory, and processing functions in the same physical units, which can compress ...
