Abstract Excitons are promising candidates for generating superfluidity and Bose–Einstein condensation (BEC) in solid-state devices, but an enabling material platform with in-built band structure advantages scaling compatibility industrial semiconductor technology is lacking. Here we predict that spatially indirect excitons a lattice-matched strained Si/Ge bilayer embedded into germanium-rich S...

The skyrmion-substrate interaction is an important issue to consider when studying particle-like skyrmions in nanostructures, which may strongly affect the skyrmion dynamics and lead complex dynamic phenomena. Here, we report current-driven behaviors of interacting with funnel obstacle a ferromagnetic layer. We computationally demonstrate that enhanced perpendicular magnetic anisotropy can be u...

Gait variability may serve as a sensitive and clinically relevant parameter to quantify adjustments in walking and the changes with aging and neurological disease. Variability of steps preceding obstacle avoidance (approach phase) are important for efficiency in the task, especially in people with Parkinson's disease (PD). However, variability of gait during the approach phase to obstacle avoid...

In this article, we report the studies of various device architectures of organic lightemitting devices (OLEDs) incorporating highly efficient blue-emitting and ambipolar carriertransport ter(9,9-diarylfluorene)s, and their influences on device characteristics. The device structures investigated include single-layer devices and multilayer heterostructure devices employing the terfluorene as one...

Solution to the safe and collision-free trajectory of the wheeled mobile robot in cluttered environments containing the static and/or dynamic obstacle has become a very popular and challenging research topic in the last decade. Notwithstanding of the amount of publications dealing with the different aspects of this field, the ongoing efforts to address the more effective and creative methods is...

Un ultimo ringraziamento va a Lui, non si gioca a dadi qui, c'` e il Suo sogno per ognuno di noi, a noi non resta che viverlo.
