Leaf Shape Variation and Its Correlation to Phenotypic Traits of Soybean in Northeast China

Fei Huang Yangjing Gan Dongdong Zhang Fei Deng Jing Peng

Leaves are the main plant organs which play an important role in plant's life. Soybean, as a major legume crop, has diverse leaf shapes among its genotypes. The motivation of this study is to analyze the leaf shape variety of 206 soybean genotypes from northeast China and its correlation to other phenotypic traits. Morphological operations have been adopted to extract the features of leaves. The results show significant differences of phenotypic traits among leaf shape groups, which indicate that the lanceolate leaf group has the highest mean plant height (89.62 cm) and the largest number of nodes per plant (15.72 nodes/plant); the round leaf group has the lowest mean 100-seed weight (18.14 g) and seed weight per plant (17.92 g); the lowest mean number of pods (41.86 pods/plant) is in the elliptical group. In terms of the maturity period, most of the lanceolate leaves (67.24%) belong to the late maturity group, in which there are only few of the elliptical leaves (11.54%). Our results suggest that the variation in leaf shape is an important indicator of other phenotypic characteristics, which could provide more information for soybean classification, as well as for cultivating new varieties in northeast China.

Proton Radiation Effects on Y-Doped HfO₂-Based Ferroelectric Memory

IEEE Electron Device Letters (2018)

Yan Wang Fei Huang Y. Hu Rongrong Cao Tuo Shi

In this letter, ferroelectric memory performance of TiN/Y-doped-HfO ₂ (HYO)/TiN capacitors is investigated under proton radiation with 3-MeV energy and different fluence (5e13, 1e14, 5e14, and 1e15 ions/cm ² ). X-ray diffraction patterns confirm that the orthorhombic phase Pbc ₂₁ of HYOfilm has no obvious change after proton radiation. Electrical characterization results demonstrate slight variations of the permittivity and ferroelectric hysteresis loop after proton radiation. The remanent polarization (2P _r ) of the capacitor decreases with increasing proton fluence. But the decreasing trend of 2P _r is suppressed under high electric fields. Furthermore, the 2P _r degradation with cycling is abated by proton radiation. These results show that the HYO-based ferroelectric memory is highly resistive to proton radiation, which is potentially useful for space applications.

Controllable Gradient in the Composition of a Ferroelectric Single Crystal

Crystal Growth & Design (2019)

Xiangda Meng Hao Tian Chengpeng Hu Yu Wang Fei Huang

Graded ferroelectric materials have attracted great attention because of their peculiar properties arising from the evolution of their microscopic structure. Graded bulk materials are advantageous because of their unique effects that can only be observed in bulk samples. A tetragonal KTa1–xNbxO3 single crystal with graded composition (GC) was designed and grown with the goal of exploring the effects of GC on the macroscopic properties of the crystal. The crystal was produced via the top-seed solution growth method. A mechanism of the formation of an internal electric field induced by GC was elucidated, and an enhancement of the strain was observed as a result of the internal electric field.

Active macroscale visible plasmonic nanorod self-assembled monolayer

Photonics Research (2018)

Yue Li Jian Li Taixing Huang Fei Huang Jun Qin

Although plasmonic nanostructure has attracted widespread research interest in recent years, it is still a major challenge to realize large-scale active plasmonic nanostructure operation in the visible optical frequency. Herein, we demonstrate a heterostructure geometry comprising a centimeter-scale Au nanoparticle monolayer and VO2 films, in which the plasmonic peak is inversely tuned between 685 nm and 618 nm by a heating process since the refractive index will change when VO2 films undergo the transition between the insulating phase and the metallic phase. Simultaneously, the phase transition of VO2 films can be improved by plasmonic arrays due to plasmonic enhanced light absorption and the photothermal effect. The phase transition temperature for Au/VO2 films is lower than that for bare VO2 films and can decrease to room temperature under the laser irradiation. For light-induced phase transition of VO2 films, the laser power of Au/VO2 film phase transition is ∼28.6% lower than that of bare VO2 films. Our work raises the feasibility to use active plasmonic arrays in the visible region.

Oxygen vacancies of YIG influence on the MPE in Au/YIG heterostructures

Xiao Liang Fei Huang Chuangtang Wang Yupeng Zhu Yan Zhang

The oxygen vacancies of Y 3 Fe 5 O 12 (YIG) influence on the magnetic proximity effect (MPE) in Au/YIG heterostructures has been studied by first principles calculations based on the density functional theory (DFT).The results show that one oxygen vacancies can reduce the two neighbor Fe 3+ to Fe 2+ and MPE in Au/YIG is strongly depended on the valence states of Fe ion.The induced magnetism in Au atoms is found to increase with the increasing concentration of Fe 2+ .In oxygen vacancy free case (Fe 3+ state), weak electron states hybridization of Fe(3d) and Au(5d) is found form the projected electron density of states distribution, while after introduce the oxygen vacancy (Fe 2+ state), the states of Fe(3d) are generally move to higher energy states and hybridize with the Au(5d) states.Moreover, more states of Fe 2+ at tetrahedral sites are hybridize with the Au(5d) states compare with that of Fe 2+ at octahedral sites, therefore a net magnetic moment induced Au atoms is found and the direction of spin polarization of Au atoms is paralleled to Fe ion at tetrahedral sites.

CeO₂-Doped Hf_0.5Zr_0.5O₂ Ferroelectrics for High Endurance Embedded Memory Applications

Zhiao Yu Balreen Saini P. J. Liao Yu-Kai Chang Vincent Hou

We demonstrate ferroelectric switching in CeO 2 doped Hf 0.5 Zr 0.5 O 2 (HZCO) thin films and their applications for back-end-of-line (BEOL) compatible embedded memories. At low cerium oxide doping concentrations (2.0 - 5.6 mol%), the polar orthorhombic phase is stabilized after annealing at temperatures below 400°C. HZCO ferroelectrics show reliable switching characteristics beyond 10 ¹¹ cycles in TiN/HZCO/TiN (MFM) capacitors, several orders magnitude higher than the identically processed Hf 0.5 Zr 0.5 O 2 (HZO) capacitors, without sacrificing polarization and retention. We also report enhanced endurance (> 10 ¹⁰ cycles) in HZCO metal-ferroelectric-insulator-semiconductor (MFIS) stacks, which is promising for ferroelectric FET memory applications.
