Ga-doped ZnO films by magnetron sputtering at ultralow discharge voltages: Effects of defect annihilation

, 2017
Preparation of high quality transparent conductive oxide (TCO) films by sputter deposition involves an intricate balance of defect generation by the highly energetic negative oxygen ions (depending on the discharge voltage) and the concomitant ...

Diketopyrrolopyrrole‐Based Cation as a Semiconducting Spacer in Layered Perovskite

Advanced Materials, EarlyView.
Diketopyrrolopyrrole cation incorporated layered perovskites exhibiting extended absorption profiles and enhanced charge carrier mobility with type‐II energy alignment. The improved photoconversion efficiency demonstrates the critical role of incorporating organic semiconductors in optimizing layered perovskite performance.

Reflections of the West in Gu Cheng’s Life and Poems

Asian Studies, 2012
Gu Cheng (1957–1993), a prominent member of the “Misty Poets”, lived the last part of his life in the West as he was exiled in 1989. So he stayed abroad separeted from his country and people and unable to cope with the western world.

The evolution of dark matter substructure [PDF]

, 2001
This thesis investigates the dynamical evolution of systems orbiting within deeper potentials. Initially we use a simple satellite-halo interaction to study the dynamical processes that act on orbiting systems and we compare these results to analytical ...

Exciton annihilation in a polyfluorene: Low threshold for singlet-singlet annihilation and the absence of singlet-triplet annihilation [PDF]

, 2007
Ultrafast photoinduced absorption measurements have been used to directly investigate singlet-singlet annihilation in polyfluorene. The pump fluence threshold for annihilation to dominate the decay was measured to be ∼1 μJ cm−2 corresponding to an ...

Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds

Advanced Materials, EarlyView.
We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.

Volatile Memristive Devices With Tunable Temporal Dynamics For Event‐Based Sensing

Advanced Materials, EarlyView.
Tunable volatile memristive devices can serve various neural‐inspired tasks that require different time windows of information retention. The ionic‐based volatility of the presented Pt/a‐STO/TaOx/Ta device stack can be reproducibly and controllably tuned in multiple ways.
