| 1 | Chromosomal-level genome of macadamia(Macadamia integrifolia)显示文摘Macadamia from the family Proteaceae is a plant native to Australia and has long been favoured by people for its crispy and high nutritional and medicinal value.Here,the genome of GUIRE 1(GR1),a highly heterozygous superior cultivar of macadamia nut,was sequenced and assembled using nanopore sequencing,and a 807-Mb genome(contig N50,1.9 Mb;scaffold N50,54.70 Mb)and 14 chromosomes were obtained.A total of 453 Mb(about 55.95%)repetitive sequences and 37,657 protein-coding genes were obtained by gene annotation and homologous protein comparison.Proteaceae diverged from Nelumbonaceae nearly 115.37 million years ago and from Rubiaceae about 140 million years ago.A genome-wide duplication(WGD)event occurred in macadamia 41 million years ago based on the WGD analysis.The functional enrichment analysis of M.integrifolia-specific gene families revealed their roles in signal transduction,protein phosphorylation,protein binding,and defense response.Here,a highly heterozygous genome of M.integrifolia was unlocked to provide a database for breeding and molecular mechanism research. | Chengcai Xia Sirong Jiang Qiujin Tan Wenquan Wang Long Zhao Chenji Zhang Yuting Bao Qi Liu Jianjia Xiao Ke Deng Miaohua He Pengliang An Wenlin Wang Meiling Zou Zhiqiang Xia | 2022 | Tropical Plants2022，1，1： | 3 |

| 4 | Intrinsic excitonic emission and valley Zeeman splitting in epitaxial MS2(M=Mo and W)monolayers on hexagonal boron nitride显示文摘Two-dimensional (2D)semiconductors,represented by 2D transition metal dichalcogenides (TMDs),exhibit rich valley physics due to strong spin-orbit/ spin-valley coupling.The most common way to probe such 2D systems is to utilize optical methods,which can monitor light emissions from various excitonic states and further help in understanding the physics behind such phenomena. Therefore,2D TMDs with good optical quality are in great demand.Here,we report a method to directly grow epitaxial WS2 and MoS2 monolayers on hexagonal boron nitride (hBN)flakeswith a high yield and high optical quality;these monolayers show better intrinsic light emission features than exfoliated monolayers from natural crystals.For the first time,the valley Zeeman splitting of WS2 and MoS2 monolayers on hBN has been visualized and systematically investigated. This study paves a new way to produce high optical quality WS2and MoS2 monolayers and to exploit their intrinsic properties in a multitude of applications. | Chunxiao Cong Chenji Zou Bingchen Cao Lishu Wu Jingzhi Shahg Haomin Wang Zhijun Qiu Laigui Hu Pengfei Tian Ran Liu Ting Yu | 2018 | Nano Research2018，11，12： | 0 |
| 5 | Probing magnetic-proximity-effect enlarged valley splitting in monolayer WSe2 by photoluminescence显示文摘Possessing a valley degree of freedom and potential in information processing by manipulating valley features (such as valley splitting),group-VI monolayer transition metal dichalcogenides have attracted enormous interest.This valley splitting can be measured based on the difference between the peak energies of σ^+ and σ^- polarized emissions for excitons or trions in direct band gap monolayer transition metal dichalcogenides under perpendicular magnetic fields.In this work,a well-prepared heterostructure is formed by transferring exfoliated WSe2onto a EuS substrate.Circular-polarization-resolved photoluminescence spectroscopy,one of the most facile and intuitive methods,is used to probe the difference of the gap energy in two valleys under an applied out-of-plane external magnetic field.Our results indicate that valley splitting can be enhanced when using a EuS substrate,as compared to a SiO2/Si substrate.The enhanced valley splitting of the WSe2/EuS heterostructure can be understood as a result of an interfacial magnetic exchange field originating from the magnetic proximity effect.The value of this magnetic exchange field,based on our estimation,is approximately 9T.Our findings will stimulate further studies on the magnetic exchange field at the interface of similar heterostructures. | Chenji Zou Chunxiao Cong Jingzhi Shang Chuan Zhao Mustafa Eginligil Lishu Wu Yu Chen Hongbo Zhang Shun Feng Jing Zhang Hao Zeng Wei Huang Ting Yu | 2018 | Nano Research2018，11，12： | 0 |
| 6 | Spatial variations of valley splitting in monolayer transition metal dichalcogenide显示文摘In monolayer group-VI transition metal dichalcogenides(TMDs),valley splitting features have received a lot of attention since it can be potentially utilized for information storing and processing.Among the known two-dimensional(2D)TMDs,monolayer WSe2 or MoSe2 has been mostly selected for excitonic and valleytronic physics studies because of its sharp and well-resolved excitonic spectral features.Meanwhile,their high optical quality leads to a tremendous desire for developing promising WSe2-and MoSe2-based valleytronic devices.Toward this goal,exploring the uniformity of valley features crossing an entire piece of monolayer becomes necessary and critical.Here,we performed the systematic magnetophotoluminescence mapping measurements on mechanically exfoliated monolayer WSe2 and observed unconventional spatial variations of valley splitting.The observed nonuniformity is attributed to the modulated doping,which is probably due to the different distributions of unintentional absorbates across the sample.Such an unexpected doping effect shows the nonnegligible influence on the valley Zeeman splitting of the trion emission(XT)while affecting that of the neutral exciton emission(X0)trivially,evidencing for the large valleytronic sensitivity of the charged exciton.This work not only enriches the understanding of the doping effect on valley splitting but also is meaningful for developing 2D valleytronics. | Chenji Zou Hongbo Zhang Yu Chen Shun Feng Lishu Wu Jing Zhang Ting Yu Jingzhi Shang Chunxiao Cong | 2020 | InfoMat2020，2，3： | 0 |
