Summary: The current-voltage characteristics of trigonal selenium nanowire crystals made via immersion in ethanol were studied, revealing a steep increase in current at the trap-filled limit voltage. Analysis based on a three-dimensional model estimated trap concentration and trap energy, compared with trap levels obtained from a photocurrent spectrum analysis. Different trap levels were attributed to deformation, OH- stretching mode, and CH- stretching mode.

Summary: The growth and optical properties of GaN quantum disks in AlN nanowires were studied via molecular beam epitaxy to control the emission wavelength of AlN nanowire-based LEDs. In addition to GaN quantum disks with thickness ranging from 1 to 4 monolayers, focus was given to incomplete GaN disks with lateral confinement. Their emission spectrum consists of sharp lines extending down to 215 nm near the AlN band edge. The room temperature cathodoluminescence intensity of GaN quantum disks embedded in AlN nanowires is about 20% of the low temperature value, highlighting the potential of ultrathin/incomplete GaN quantum disks for deep UV emission.

Summary: Nanopores are used as versatile single-molecule sensors for complex mixtures of structured molecules, such as molecular data storage and disease biomarker detection. However, analyzing nanopore data becomes more challenging with increased molecular complexity, including rejection of translocation events not matching the expected signal structure and selection bias entering the event curation process. In this study, the analysis of a model molecular system using a nanostructured DNA molecule attached to a linear DNA carrier is presented, highlighting the challenges and proposing refinements to improve the analysis techniques.
