Diced and grounded broadband bow-tie antenna with tuning stub for resonant tunnelling diode terahertz oscillators [PDF]

open access: yes, 2016
Radiation from antennas integrated with indium phosphide (InP)-based resonant tunnelling diode (RTD) oscillators is mainly through the substrate because of the effects of the large dielectric constant.

Terahertz Radiation Effects and Biological Applications

open access: yesJournal of Infrared, Millimeter, and Terahertz Waves, 2009
We present a brief overview of the literature on biological applications and experimental data on the effects of THz radiation. The region of the electromagnetic spectrum from 0.1 to 10 THz is a frontier area for research in physics, chemistry, biology, materials science and medicine. This area has recently begun to be filled by a variety of sources of

Unlocking Multi‐Valley Energy Pockets and Interface‐Induced Phonon Filtering in InSb Thermoelectrics by Reaction‐Driven Interface Engineering

open access: yesAdvanced Functional Materials, EarlyView.
InSb, a narrow‐bandgap semiconductor with high carrier mobility, is promising for thermoelectric energy conversion but suffers from high lattice thermal conductivity and strong bipolar conduction. Here, in situ interface engineering using Co2O3 nanoprecursors forms hierarchical CoSbx/In2O3/CoSb3 heterostructures that enhance phonon scattering and ...

Trends in the applications of terahertz radiation in oral oncology treatments

open access: yesOral Oncology Reports
In Terahertz radiation, known as THz-rays, falls within a special range of frequencies in the electromagnetic spectrum, from 0.1 to 10 THz. This radiation has unique benefits for medical imaging, security screening, and non-destructive testing.

The Conjugate Gradient Least Square Algorithm in Terahertz Tomography

open access: yesIEEE Access, 2021
Terahertz tomography allows for non-contact tomographic inspection of dielectric materials without the need for radiation protection measures. Terahertz tomography offers the opportunity to inspect such objects from multiple angles not only by measuring ...

Modeling DNA response to terahertz radiation [PDF]

open access: yesPhysical Review E, 2011
Collective response of DNA to terahertz electric fields is studied in a simple pair bond model. We confirm, with some caveats, a previous observation of destabilizing DNA breather modes and explore the parameter dependence of these modes. It is shown that breather modes are eliminated under reasonable physical conditions and that thermal effects are ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
