Detailed studies of the interlayer Seebeck effect of organic conductor ฮฑ-(BEDT-TTF)2KHg(SCN)4 as a function of temperature, magnetic field strength, and field orientation are reported. We find that the formation of the CDW0 state is mainly due to the Fermi surface reconstruction as a result of the magnetic breakdown effect since the onset magnetic field for this state is near the magnetic...

Using Thermionic Vacuum Arc technology were created nanostructured thin films using four material: graphite, titanium, silicon, and aluminum, with the inclusion of nitrogen, on the Si substrate. TDS analysis reveal the presence of nitrogen in all cases. The Raman spectra show that the nitrogen treatment of the films leads to the formation of nitrides for each compound. The infrared absorption...

In nano-electronic technology, the overall thermal reliability is recognized by the temperature of the hottest zone on the die. Accordingly, the transistor with a lower maximum temperature is easier kept under the working threshold temperature. Thus, the material selection and also the heat spreader design, as the thermal management solutions for controlling the temperature of the hotspots,...

We report results of computational studies investigating the electron transfer between the dye and the TiO2 nanocluster as well as between the electrolyte and the dye, to understand the mechanisms that influence the performance of dye-sensitized solar cells. By means of density functional theory calculations, we determine the parameters of Marcusโ theory for charge transfer from a...

We have studied theoretically the effect of interfacial Rashba spin-orbit coupling (SOC) on the Josephson effect between two $d$-wave superconductors with ferromagnetic layer in between, based on the Bogoliubov-de Gennes approach, extended McMillanโs Green function formalism, and generalized Furusaki-Tsukada treatment. If both time-reversal and space-inversion symmetries are broken, Josephson...

Recent interest in quantum dynamics of electronic excitations in molecular semiconductors and photosynthetic molecular aggregates [1] is motivated by the prospect of optoelectronic applications that could harness quantum effects and enhance charge and energy transport. Typically, the coupling of charges or excitons to quantum lattice vibrations lies in the intermediate regime, whose reasonable...

4. Theoretical Insight into Strongly Suppressed Thermal Conduction in Fully Dense Crystalline SolidsYue Chen (The University of Hong Kong)10/07/2025, 12:00S03 โ Condensed matter, Materials and Applied PhysicsOral Presentations
The thermal properties of materials are important for the development of various modern technologies. In particular, thermoelectric energy conversion and thermal barrier require materials with ultra-low thermal conductivity. Lattice vibration dominates heat transport in insulating solids; recent theoretical studies suggested that both propagation and diffuson-like behaviors of phonons can play...

The effect of the interaction of nonlinear excitations with extended inhomogeneities in an on-site anisotropic Heisenberg spin chain is probed numerically. Inhomogeneity corresponds to a segment consisting of consecutive spins on the chain that are subjected to an inhomogeneous magnetic field. To describe the behavior of the spin chain, we derive the nonlinear Schrรถdinger equation (NLS) of the...

High bandgap materials like fused silica and soda-lime glass are widely utilized in optics, optoelectronics, and microfluidics due to their advantageous properties, such as transparency, thermal stability, and chemical resistance. However, conventional methods of processing these materials pose significant challenges. Ultrashort pulse lasers are now essential for precise micromachining of...

Abstract. Frenkel excitons (FEs) as collectivized electronic excitations are studied using the models of two-strands regular structures with B-DNA geometry. As basic excitations we consider the excitations of the pairs of complementary bases, not the excitations of separate bases, because of the following reasons: 1. Permanent pairing of complementary bases A-T and C-G; 2. Small inter-bases...

Nowadays Si-wafer based PV technology accounted for more than 95% of the total production. The market share of mono-crystalline technology is about 84% of total c-Si production. In order to meet the low-cost manufacturing criterion the Czochralski (CZ) crystal growth method which is the dominant technology for growing high quality monocrystalline silicon should be optimized. Defects and...

High-temperature corrosion protection of low-alloy steel in steam generators of nuclear power plants is provided by a layer of magnetite. The presence of various small molecules in the cooling system affects the flow-assisted corrosion processes. The molecular dynamics (MD) method allows for an in-depth analysis of the mechanism and extent of adsorption of such molecules on magnetite at the...

Groundwater is the lifeline of tap water for many cities in Albania, but its safety depends on regular assessments of its chemical quality. Pollution and overuse can silently affect its quality, putting both peopleโs health and the environment at risk. Safeguarding this essential resource aligns with SDG 6, which calls for the protection and sustainable management of water for current and...

MoSe2 layered crystals intercalated with iodine (MoSe2:I2) exhibit distinct photoluminescence (PL) due to excitons bound to the halogen molecules, which form neutral isoelectronic centers in the van der Waals gap [1]. At low temperatures, the luminescence is dominated by two sharp zero-phonon lines (ZPLs) labeled A and B at 1.036 and 1.042 eV, respectively, due...
