The passivation influence by ligands coverage with trioctylphosphine oxide (TOPO) and TOPO including colloidal CdSe/ZnS quantum dots (QDs) on optical properties of the semiconductor heterostructure, namely an array of InP nanowires (NWs) with InAsP nanoinsertion grown by Au-assisted molecular beam epitaxy on Si (111) substrates, was investigated. A significant dependence of the photoluminescence (PL) dynamics of the InAsP insertions on the ligand type was shown, which was associated with the changes in the excitation translation channels in the heterostructure. This change was caused by a different interaction of the ligand shells with the surface of InP NWs, which led to the formation of different interfacial low-energy states at the NW-ligand boundary, such as surface-localized antibonding orbitals and hybridized states that were energetically close to the radiating state and participate in the transfer of excitation. It was shown that the quenching of excited states associated with the capture of excitation to interfacial low-energy traps was compensated by the increasing role of the “reverse transfer” mechanism. As a result, the effectiveness of TOPO-CdSe/ZnS QDs as a novel surface passivation coating was demonstrated.

AbstractThis article explores a forcible, wartime transfer of women and minors from one ethnic group to another, and its partial reversal after the war. I analyze the historical conditions that enabled the original transfer, and then the circumstances that shaped the reverse transfer. The setting is Istanbul during and immediately after World War I, and the protagonists are various influential agents connected to the Ottoman Turkish state and to the Armenian Patriarchate. The absence and subsequent involvement of European Great Powers determines the broader, shifting context. The narrative follows the bodies of women and children, who were the subjects of the protagonists' discourses and the objects of their policies. This is the first in-depth study to connect these two processes involved: the wartime integration of Armenian women and children into Muslim settings, and postwar Armenian attempts to rescue, reintegrate, and redistribute them. I explain why and how the Armenian vorpahavak (gathering of orphans and widows) worked as it did, and situate it comparatively with similar events. I highlight its uniqueness, and the theoretical possibilities that it offers toward understanding why and how women, children, and reproduction matter to collectivities in crisis.

We investigate a cascode configuration of a normally-on SiC-Buried Gate Static Induction Transistor (SiC-BGSIT) and Si-MOSFET as an alternative switching device of the SiC-MOSFET. It is shown that the transconductance of our cascode device is much higher than that of commercial SiC-MOSFETs while the switching speed is much faster than that of normally-off SiC-BGSITs. The origin of the fast switching speed in this cascode configuration is discussed in terms of a simulated reverse transfer capacitance.
