Moving beyond the limits of silicon transistors requires both a high-performance channel and high-quality electrical contacts. Carbon nanotubes provide channels below 10 nanometers, but as with silicon, increase in contact resistance decreasing size becomes major performance roadblock. We report single-walled carbon nanotube (SWNT) transistor technology an end-bonded scheme that leads to size-independent overcome scaling conventional side-bonded or planar schemes. A SWNT was fabricated...
Highly efficient green and red electro-phosphorescence is achieved in devices with the host material DPESPODEF3. The multiple fluorenyl moieties of are arranged such that it has an unsymmetrical molecular configuration, its triplet-state location tuned independent energy (ET) charge transfer (CT) channels. As a result, DPESPODEF3 can suppress triplet-triplet annihilation triplet-polaron quenching. In resulting phosphorescent devices, impressive external quantum efficiencies ca. 20% 16% power...
The electron-doping-induced phase transition of a prototypical perovskite SmNiO3 induces large and non-volatile optical refractive-index change has great potential for active-photonic-device applications. Strong modulation from the visible to mid-infrared is demonstrated using thin-film . Modulation narrow band light plasmonic metasurfaces integrated with
An ambipolar ternary deep-blue emitter with CIE coordinates of (0.15, 0.07) and high electroluminescent performance was constructed on the basis an insulated donor–π–acceptor system through indirect linkage.

With the aim to rationally figure out significance of charge and exciton capture in electrophosphorescent processes low-triplet-energy hosts involved doping systems, frontier molecular orbital (FMO) energy levels a series with diphenylphosphine oxide (DPPO) triphenylamine (TPA), collectively named DPExPOTPAn, were successfully gradually tuned on basis their constant triplet (T1) 2.63 eV get rid interference from host-dopant transfer. It was showed that device efficiencies directly...
Theoretical accounts assume that key features of human social cognition are universal. Here we focus on gaze-following, the bedrock interactions and coordinated activities, to test this claim. In comprehensive cross-cultural study spanning five continents 17 distinct cultural communities, examined development gaze-following in early childhood. We identified processing signatures through a computational model assumes participants follow an individual’s gaze by estimating vector emanating from...

Specific emitter identification is the process of identifying or discriminating different emitters based on radio frequency fingerprints extracted from received signal.Due to inherent non-linearities power amplifiers emitters, these features are for specific identification.In this paper, we take 433MHz amplifier module BLT54A as research object, eight circuit modules with same specifications and batches were tested.The experimental contents include: S parameters, AM-AM curve, AM-PM input...
Polymeric materials, including polyethylene terephthalate (PET), are widely used in various fields because of their beneficial properties. Functional films deposited on these materials through different approaches, such as plasma-enhanced atomic layer deposition (PEALD), to enhance performance and prolong life span. However, the inert thermally fragile nature most polymers hinders deposition. We developed a strategy for PEALD nanoscale Al2O3films PET substrates. First, substrate is subjected...
