Summary: This research investigates the carrier injection effect in hybrid structures with SQDs coupled to either BQDs or a QW injection layer. The study finds that carrier capture and emission efficiency for SQDs in the BQD injection structure is better than that of the QW injection due to strong coupling between the two QD layers.

Summary: By combining size-resonant light concentration, tapered shape, and favorable scattering geometry, the Raman signal of surface phonon polaritons (SPhPs) can be enhanced by orders of magnitude in GaAs semiconductor nanowires. This enhancement allows for detailed characterization of SPhPs on an individual nanowire level, revealing polarization properties and spectral shifts under varying dielectric environments.

Summary: Control over doping at the nanoscale during nanostructure growth is crucial for device fabrication. This study investigates the p (Zn)- and n (Sn)- doping distributions and the formation of 3D p-n junctions in planar GaAs nanowires grown on doped GaAs substrates. Various techniques, including scanning electron microscopy, transmission electron microscopy, and conductive atomic force microscopy, are used to analyze the nanowire morphology and doping distribution. The results show that bipolar transistor-like lateral nanostructures can be formed during p-n or n-p growth on misoriented (001) GaAs substrates, while core-shell field effect transistor-like structures can be synthesized on singular (001) substrates. The effects of substrate misorientation on 3D doping distribution are attributed to the preferential incorporation of dopants in polar side facets compared to a non-polar top (001) facet.

Summary: We investigate the surface and interface engineering on InAs quantum dot emitters using edge-emitting light-emitting diodes encapsulated with non-stoichiometric silicon nitride (SiN) layers. Our findings show that silicon-rich SiN is an excellent choice for both electrical and optical passivation, reducing surface recombination. However, N-rich SiN deposited by the same method does not provide effective passivation under electrical injection. This research provides important insights for the monolithic integration of InAs quantum dot emitters with CMOS photonics components.

Summary: Control of interfacial physicochemical properties related to device materials to reduce the impact of point defects on device performance is a key focus in the semiconductor industry. While control of defect density for silicon has been established through deliberate reactions with congruent species, such as hydrogen, the control of interfacial defects for III-V device materials remains an active area of research. III-V devices have demanding performance criteria, and surface reactions of III-V crystals, including oxidation, can limit device performance, resulting in significant degradation.

Summary: The relationship between the presence of undercoordinated surface atoms and the formation of localized trap states in InP quantum dots was analyzed using density functional theory. Removal of the surface passivation can lead to the formation of hole traps linked to 2-coordinated surface P and electron traps related to 2- or 3-coordinated surface P and 2-coordinated surface In. The concept of ionicity provides little guidance to understand the enhanced sensitivity of InP to trap-state formation, suggesting the need for more appropriate descriptors to predict the energetic position of atomic orbitals relative to band-edge states.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
