Special Issue Information

Dear Colleagues,

As Editor-in-Chief of the journal Quantum Beam Science (ISSN 2412-382X), it is my pleasure to announce the launch of a new Special Issue entitled “Quantum Beam Science: Feature Papers 2025”. QuBS is an international, open access journal publishing reviews and original research focusing on the application of quantum beams to the study and characterization of materials in their widest sense, as well as developments in quantum beam sources, instrumentation, and facilities. In this Special Issue, we will publish outstanding contributions in the primary fields covered by the journal, something which we believe will make a great contribution to this research community. The entire Special Issue will be published in book format after its completion.

Quantum beams include synchrotron radiation, X-rays, gamma rays, neutron beams, electrons, lasers, muons, positrons, ions, and extremely strong lasers, while materials can be crystalline, amorphous, magnetic, metallic, ceramic, biologic, hard or soft matter, warm dense matter, functional, structural, and so on. Quantum beam science covers a broad range of disciplines including, but not limited to, solid-state physics, chemistry, crystallography, materials science, biology, geology, earth and planetary materials, and engineering. Examples of investigation topics include phase transformations in alloy development, modulated structures in spintronic systems, crystalline order and disorder, stresses in engineering specimens, changes in amorphous structure, excitations in functional materials, the interior of stars, electrochemistry in ion battery systems, imaging in life sciences, and the propagation of dislocations in crystals.

Submissions are encouraged to present multiple quantum beams for complementary studies, such as neutron and synchrotron radiation or muons and neutrons. Instrumental publications should cover large user facilities, novel developments, sources, spectrometers, diffractometers, functionality, physical- and optical-based backgrounds, scattering, and interaction theories with respect to the application and the fundamentals of the probe.

Submitted papers will be evaluated by the Editors first. Please note that all papers will be subjected to a thorough and rigorous peer review.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Quantum Beam Science is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Optimizing thermoelectric (TE) performance in two-dimensional materials has emerged as a pivotal strategy for sustainable energy conversion. This study systematically investigates the regulatory mechanisms of uniaxial strain (−2% to +2%), temperature (300–800 K), and out-of-plane electric fields (0–1.20 eV/Å) on the thermoelectric properties [...] Read more.
Optimizing thermoelectric (TE) performance in two-dimensional materials has emerged as a pivotal strategy for sustainable energy conversion. This study systematically investigates the regulatory mechanisms of uniaxial strain (−2% to +2%), temperature (300–800 K), and out-of-plane electric fields (0–1.20 eV/Å) on the thermoelectric properties of monolayer MoS2 via first-principles calculations combined with Boltzmann transport theory. Key findings reveal that uniaxial strain modulates the bandgap (1.56–1.86 eV) and carrier transport, balancing the trade-off between the Seebeck coefficient and electrical conductivity. Temperature elevation enhances carrier thermal excitation, boosting the power factor to 28 × 1010 W·m−1·K−2·s−1 for p-type behavior and 27 × 1010 W·m−1·K−2·s−1 for n-type behavior at 800 K. The breakthrough lies in the exceptional suppression of lattice thermal conductivity (κ1) by out-of-plane electric fields—at 1.13 eV/Å, κ1 is reduced to single-digit values (W·m−1·K−1), driving ZT to ~4 for n-type MoS2 at 300 K. This work demonstrates that synergistic engineering of strain, temperature, and electric fields effectively decouples the traditional trade-off among the Seebeck coefficient, conductivity, and thermal conductivity, providing a core optimization pathway for 2D thermoelectric materials via electric field-mediated κ1 regulation.
