Physics Today

Physics Today is the official magazine of the American Institute of Physics, founded in 1948. It is distributed to members of ten different physics societies, including the American Physical Society. While it offers scientifically sound and current information, it does not function as a traditional research journal for sharing new findings. Instead, it serves as a hybrid publication that keeps readers updated on significant advancements through expert overview articles, concise reviews written by its own staff, and discussions on current issues affecting the scientific community, such as science policy. For the latest research results, the physics field primarily relies on the Physical Review series of journals published by the American Physical Society and Applied Physics Letters from the American Institute of Physics.

Kirchhoff's law violation within the main solar wavelength range

Dec 10, 2024 | pubs.aip.org | Ginzton Laboratory |Sebastian Schulz |Christina M. Rost

Recently, nonreciprocal structures that violate Kirchhoff's law of thermal radiation have attracted considerable interest for their potential in solar energy harvesting applications. However, previous research has primarily focused on mid-infrared wavelengths rather than on the main solar wavelength range where sunlight intensity is concentrated.
Navigating the challenges: A comprehensive review of biomedical waste management practices

Dec 10, 2024 | pubs.aip.org | Apu Kowsar |Yu. N. Melikova

Biomedical waste management is a critical public health and environmental safety nexus, demanding comprehensive understanding and action. In this review article, we navigate the multifaceted landscape of biomedical waste, delving into its types, challenges, regulatory frameworks, and the role of healthcare personnel. The significance of proper management is underscored through evidence of environmental contamination and health risks resulting from inadequate practices.
The impact of P-type doping level and profile on performance of InAs quantum dot lasers

Dec 10, 2024 | pubs.aip.org | Optoelectronics Engineering |Grzegorz Greczynski |Cyrus E. Dreyer

In light of the exponential growth in global data throughput, it is important that modern communication systems are realized by faster, cheaper, and more efficient data transmission methods.1,2 Si-based photonic integrated circuits (PICs) are good candidates to meet these requirements, offering high bandwidth for data transmission while achieving economic efficiency.3–10 However, the advancement of Si-based on-chip light sources, a pivotal component of Si-based PICs, has been hindered by the...
Electric field management in β-Ga2O3 vertical Schottky diodes using high-k bismuth zinc niobium oxide

Dec 10, 2024 | pubs.aip.org | Sebastian Schulz |Christina M. Rost

In this work, we have integrated bismuth zinc niobium oxide (BZN), a high-k dielectric material, in metal–insulator–semiconductor (MIS) and field-plated metal–semiconductor (FP-MS) Schottky barrier diodes on -Ga O . This increases the breakdown voltage (⁠ ⁠) from 300 to 600 V by redistributing the electric fields, leveraging the high permittivity of BZN (k 210).
Impact of reduced spectral resolution on temporal-coherence-based source segregation

Dec 10, 2024 | pubs.aip.org | Carnegie Mellon |Maïa Ponsonnet |Pierre-Amaury Grumiaux |Wesley Grantham

Hearing-impaired listeners struggle to understand speech in noise, even when using cochlear implants (CIs) or hearing aids. Successful listening in noisy environments depends on the brain's ability to organize a mixture of sound sources into distinct perceptual streams (i.e., source segregation). In normal-hearing listeners, temporal coherence of sound fluctuations across frequency channels supports this process by promoting grouping of elements belonging to a single acoustic source.

Nucleation study of AlN crystal growth on 6H-SiC substrates using the MOCVD

Dec 10, 2024 | pubs.aip.org | Sebastian Schulz |Christina M. Rost

Topics Molecular dynamics, Crystallographic defects, Crystal structure, Crystallography, Thin film growth, Chemical vapor deposition, Chemical bonding Over the past few decades, III-nitrides have garnered widespread attention due to their outstanding optoelectronic and physical properties.1–3 Attribute to their tunable bandgap (3.4–6.2 eV),4 aluminum nitride (AlN) is frequently used as a buffer layer for ultraviolet light-emitting diodes (UV LEDs)5,6 and high electron mobility transistors...
Dielectric properties of nanoconfined water

Dec 10, 2024 | pubs.aip.org | Jinzhe Zeng |Miguel Jorge |Philipp Pracht

The dielectric function of a dipolar liquid exhibits a strong wavenumber dependence in the bulk homogeneous state. Such a behavior seems to suggest the possibility of a strong system size dependence of the dielectric constant (DC) of a nanoconfined liquid, although details have been revealed only recently.
Developing techniques for interactive 3D visualization of medical data to aid surgical planning and education

Dec 10, 2024 | pubs.aip.org | Apu Kowsar |Yu. N. Melikova

Modern interactive 3D visualization tools and medical imaging have been combined in recent years, revolutionizing surgery planning and medical education. The creation of novel approaches to use interactive 3D visualization for improving comprehension of complex medical data, assisting surgical planning, and boosting medical education is explored.
