The distribution of electric current on capacitive electrodes in electrolyte is of great interest in electrochemistry in general, and in bioelectronics in particular. This problem has been addressed numerically, for specific geometries; now, borrowing methods from quantum mechanics, the authors develop an analytical solution for any electrode geometry, and describe the dynamics of current redistribution from the initial equipotential boundary to a steady state where current density is proportional to capacitance per unit area. Experiment validates this theoretical result. These findings provide intriguing insights regarding innovative designs of electrodes for electroneural interfaces composed of different materials.

The mixed-valence gold iodide CsAuI shows promising photovoltaic properties, such as excellent simulated absorption and low exciton binding energy. The authors use hybrid density functional theory to evaluate the family of inorganic and organic gold mixed-valence halides from a photovoltaic perspective. While all of these inorganic halides exhibit high efficiency, several deep-level defects are possible, which may hinder practical performance. These results should provide the basis for further studies of these materials, and help our overall understanding of defect physics in this class of lead-free perovskites for solar power.

In extending the ideas of topological phases of matter to acoustic and mechanical systems, a quasiperiodic arrangement of resonators introduces frequency band gaps in addition to the locally resonant gap. Here numerical evaluation of the spectrum as a function of the quasiperiodic arrangement reveals a structure reminiscent of the famous Hofstadter butterfly. The onset of the locally resonant band gap and topologically nontrivial gaps with associated edge states is demonstrated numerically and experimentally. These structural designs can induce wave localization and attenuation over multiple frequency bands, for applications in vibration isolation and energy harvesting.

The temporal structures of ultrashort optical pulses are key to the study of ultrafast phenomena. The authors demonstrate an all-optical method for time-domain characterization of an ultrashort optical pulse. Utilizing nonionizing lasers to induce the ac Stark effect in a helium atom, by interrogating the quasienergies of the laser-dressed atom using extreme-ultraviolet attosecond pulses, the waveform of an optical pulse can be precisely diagnosed. Using a nonionizing laser minimizes plasma-induced pulse distortion, and provides a complementary detection scheme for an effective and reliable “optical oscilloscope”.

In conventional theoretical methods for studying dissipative quantum transport, numerical complexity forces us to ignore important nonlocal effects, or to restrict attention to very small or one-dimensional systems. The authors present an efficient method, based on the Pauli master equation, that treats dissipative quantum transport while explicitly taking into account the nonlocal and inelastic nature of the scattering processes. Applying the method to a realistic semiconductor device reveals that, even at the nanoscale, electronic transport is predominantly dissipative, and demonstrates quantitatively that scattering due to interface roughness has a drastic impact on device performance.

The current interest in non-Hermitian physics calls for a simple, reliable experimental technique to investigate energy-momentum relationships at high resolution in angle and frequency. To this end, the authors present angle-resolved thermal emission spectroscopy (ARTES), a technique that does not use the external energy sources required by conventional methods. Utilizing symmetry and radiation losses, they demonstrate several non-Hermitian dispersion features, such as non-Hermitian bulk Fermi arcs and exceptional lines, via ARTES in a synthetic parameter space. With this approach, the band-structure mapping of complicated non-Hermitian structures becomes relatively straightforward.

Electron-phonon coupling (EPC) in nanostructures has emerged as a critical issue in nanoscience. The change in EPC from the bulk value is pertinent in phonon bottleneck, multiexciton generation, hot-electron solar cells, and laser cooling. Many ambiguous or contradictory results have been reported in the last 30 years. The authors show unambiguously that there is very little change in EPC in ZnTe nanowires, down to 30 nm in diameter; however, EPC is tunable (“programmable”), either during or after material growth, for both bulk and nanostructures. This study enables the development of practical applications and theories of EPC in reduced dimensions.

Gas detection is important in many endeavors, including healthcare, security, environmental science, and the semiconductor industry. Electronic gas detection can be highly sensitive, but its major drawback is poor , the ability to distinguish various analytes in a gas mixture. Here researchers explore theoretically the possibility of optical gas detection via plasmons in graphene. They discuss the trapping of molecules on a graphene nanoribbon via adsorption and optical and electrostatic fields, and how these approaches allow for plasmon-based detection with enhanced spectroscopic sensitivity.
