Summary: The surface and lithium diffusion properties of Si(100) doped with B and P were studied using the first-principles plane wave pseudopotential method. The calculations showed a greater effect of B-doping compared to P-doping on Si(100)-7. The presence of P reduced the diffusion barrier for Li atoms, as observed in the simulation results of multiple Li atom diffusion.

Summary: The non-trivial topology of three-dimensional topological insulators leads to the appearance of unique gapped Dirac sub-band structures in nanowires, which are important for future Majorana qubits. These quantized sub-bands can be observed by tuning the chemical potential in the gate-voltage dependence of the resistance.

Summary: The study investigates the quantum confinement effect in SiNWs fabricated by SIE technique, showing an enhanced optical band gap under UV excitation. The analysis of characteristic features of Raman line-shape helps to understand the mechanism of QC effect, and different models are used to calculate the NCS of SiNWs in the samples. This research suggests a new direction for fabricating optoelectronic devices based on nano-scale light-matter interactions.

Summary: In this study, the electrical and optical properties of single GaN nanowire p-n junctions grown by plasma-assisted molecular-beam epitaxy using magnesium and silicon as doping sources were analyzed. The results showed that parasitic radial growth enhanced by magnesium doping led to fluctuations in the junction position and shape, while reverting the doping order resulted in a more stable structure and better optical quality. Additionally, a high hole concentration in the p-doped segment was achieved without degrading the nanowire morphology.

Summary: This article introduces a simple technique to achieve p-type and n-type materials based on the same semiconductor using an isoelectronic surface dopant. By surface functionalization, thin p-type colloidal Bi2Te3 nanowires can be switched to n-type, thus increasing the availability of new nanocrystalline solution-processable p-n homojunctions.

Summary: In this study, a catalyst with high activity and stability was successfully prepared by functionalizing the surface of the electrode with 2,6-diaminopyridine for photoassisted electrochemical CO2 reduction toward CO. The proposed synergistic mechanism facilitates the reduction of CO2 to produce CO and inhibits the competitive hydrogen evolution reaction.

Summary: In this study, 2,6-diaminopyridine (2,6-DAP) was used for the first time to functionalize the electrode surface, resulting in a p-Si/Ag/2,6-DAP electrode with high activity and CO selectivity. The optimized potential for CO production was found to be -0.9 V vs RHE, with a Faradaic efficiency of 84.56%. A synergistic mechanism involving the reduction of CO2 by Ag and the adsorption of CO2 by 2,6-DAP was proposed to explain the enhanced catalytic performance of p-Si/Ag/2,6-DAP.

Summary: This work presents the selective area epitaxy of GaN nanostructures grown on Ga-polar GaN/sapphire substrates by plasma-assisted molecular beam epitaxy. Three types of nanostructures, namely nanowires, nanofins, and nanorings, are demonstrated on GaN-on-sapphire templates, with investigation on the control of their morphology and orientation. This study advances the understanding of selective area epitaxy for defining complex III-nitride nanostructures, which are important in the fields of nanotechnology and nanoscience.
