Quantum Criticality and the Kondo Lattice

open access: yes, 2010
Quantum phase transitions (QPTs) arise as a result of competing interactions in a quantum many-body system. Kondo lattice models, containing a lattice of localized magnetic moments and a band of conduction electrons, naturally feature such competing ...

Terahertz fibre transmission link using resonant tunnelling diodes integrated with photonic‐crystal waveguides

open access: yesElectronics Letters, Volume 55, Issue 7, Page 398-400, April 2019., 2019
The authors present an expanded porous polytetrafluoroethylene terahertz fibre transmission link using resonant tunnelling diodes integrated with photonic‐crystal waveguides as a transmitter and a receiver. The measured coupling efficiency between the terahertz fibre and the photonic‐crystal waveguide integrated with a silicon tapered coupler is ∼30 ...

Endotaxial Si nanolines in Si(001):H

open access: yes, 2011
We present a detailed study of the structural and electronic properties of a self-assembled silicon nanoline embedded in the H-terminated silicon (001) surface, known as the Haiku stripe.

Assault on self: intimate partner abuse and the contestation of identity [PDF]

open access: yes, 2011
The complexities of intimate partner abuse and violence have been studied from a range of theoretical, conceptual, and methodological perspectives. It is argued here that symbolic interactionist analyses offer specific and powerful insights into this ...

Impact of the Si Electrode Morphology and of the Added Li‐Salt on the SEI Formed Using EMIFSI‐Based Ionic‐Liquid Electrolytes

open access: yesAdvanced Sustainable Systems, Volume 9, Issue 8, August 2025.
The early‐stage formation and evolution of the solid electrolyte interphase (SEI) on binder‐free silicon electrodes is investigated by advanced spectroscopic techniques and controlled galvanostatic cycling. The influence of electrode crystallinity and morphology on passivation film composition and thickness is demonstrated, offering valuable insights ...

Continuous provision of synthetic inertia with wind turbines: implications for the wind turbine and for the grid

open access: yesIET Renewable Power Generation, Volume 13, Issue 5, Page 668-675, April 2019., 2019
In future power systems with little system inertia, grid operators will require the provision of synthetic inertia (SI) from renewable energy sources. Unlike today, grid operators may require continuous provision of SI. This can lead to an unwanted disconnection of wind turbine generators (WTGs) from the grid, and has the potential to cause a ...

Metrisering

open access: yesSouth African Journal of Business Management, 1970
South Africa is at present experiencing a radical change by the introduction of the metric system. In this article, the advantages of the modern internationally accepted metric system (S.I.) are sketched.

5009‐ppi, 10000‐cd/m2, OLED/OS/Si structure display with built‐in CPU and display driver

open access: yesJournal of the Society for Information Display, Volume 33, Issue 5, Page 314-323, May 2025.
This study developed a 5,009‐ppi, 10,000‐cd/m2 organic light‐emitting diode display featuring c‐axis‐aligned crystalline oxide semiconductor field‐effect transistors (FETs) monolithically stacked over silicon (Si) FETs. It was demonstrated that a built‐in central processing unit (Cortex‐M0) enables amplifier offset compensation and that functional ...

Influence of the clamping force on the power cycling lifetime reliability of press pack IGBT sub‐module

open access: yesThe Journal of Engineering, Volume 2019, Issue 16, Page 2435-2439, March 2019., 2019
The clamping force is the most important parameter of Press Pack IGBTs (PP IGBTs) as it not only affects the electrical, thermal, and mechanical characteristic, but also the long lifetime reliability. Too little clamping force increases the contact resistance and junction temperature.
