| 1 | 二维材料最新研究进展显示文摘Research on two-dimensional(2D) materials has been explosively increasing in last seventeen years in varying subjects including condensed matter physics, electronic engineering, materials science, and chemistry since the mechanical exfoliation of graphene in 2004. Starting from graphene, 2D materials now have become a big family with numerous members and diverse categories. The unique structural features and physicochemical properties of 2D materials make them one class of the most appealing candidates for a wide range of potential applications. In particular, we have seen some major breakthroughs made in the field of 2D materials in last five years not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing forward commercialisation. In this review, we provide a critical summary on the recent progress made in the field of 2D materials with a particular focus on last five years. After a brief backgroundintroduction, we first discuss the major synthetic methods for 2D materials, including the mechanical exfoliation, liquid exfoliation, vapor phase deposition, and wet-chemical synthesis as well as phase engineering of 2D materials belonging to the field of phase engineering of nanomaterials(PEN). We then introduce the superconducting/optical/magnetic properties and chirality of 2D materials along with newly emerging magic angle 2D superlattices. Following that, the promising applications of 2D materials in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially. Thereafter, we present the theoretic calculations and simulations of 2D materials. Finally, after concluding the current progress, we provide some personal discussions on the existing challenges and future outlooks in this rapidly developing field. | 常诚 陈伟 陈也 陈永华 陈雨 丁峰 樊春海 范红金 范战西 龚成 宫勇吉 何其远 洪勋 胡晟 胡伟达 黄维 黄元 季威 李德慧 李连忠 李强 林立 凌崇益 刘鸣华 刘楠 刘庄 Kian Ping Loh 马建民 缪峰 彭海琳 邵明飞 宋礼 苏邵 孙硕 谭超良 唐智勇 王定胜 王欢 王金兰 王欣 王欣然 Andrew T.S.Wee 魏钟鸣 吴宇恩 吴忠帅 熊杰 熊启华 徐伟高 尹鹏 曾海波 曾志远 翟天佑 张晗 张辉 张其春 张铁锐 张翔 赵立东 赵美廷 赵伟杰 赵运宣 周凯歌 周兴 周喻 朱宏伟 张华 刘忠范 | 2021 | 物理化学学报2021，37，12： | 9 |
| 2 | Van der Waals magnets: Wonder building blocks for two-dimensional spintronics?显示文摘The unprecedented realization of two-dimensional(2D)van der Waals magnets excitingly extends the synergy between spintronics and 2D materials,started with graphene over the last decade.This article reviews the recent milestones in the development of 2D magnets and its derived heterostructures.In particular,a number of critical challenges centered around the scalability,ambient stability and Curie temperature of these atomically thin magnets are discussed.This mini-review also provides an outlook on what the future might hold for this integrated field of 2D spintronics,and assesses its potential in postsilicon electronics. | Wen Zhang Ping Kwan Johnny Wong Rui Zhu Andrew T.S.Wee | 2019 | InfoMat2019，1，4： | 8 |
| 3 | Two-dimensional magnetic transition metal chalcogenides显示文摘The field of two-dimensional(2D)magnets has expanded rapidly during the past several years since the first demonstration of intrinsic 2D magnetism in atomically thin CrI_(3) and Cr_(2)Ge_(2)Te_(6) in 2017.2D transition metal chalcogenides(TMCs),a class of strongly correlated materials,have exhibited a wide variety of novel electronic and optical properties,and more recently magnetism.Here,we review recent experimental progress achieved in the growth of 2D magnetic TMC materials using chemical vapor deposition and molecular beam epitaxy methods.Outstanding examples include the demonstration of room temperature intrinsic and extrinsic ferromagnetism in monolayer VSe_(2),MnSe_(2),Cr_(3)Te_(4),V-doped WSe_(2),and so on.A brief discussion on the origin of the exotic magnetic properties and emergent phenomena is also presented.Finally,we summarize the remaining challenges and future perspective on the development of 2D magnetic materials for next-generation spintronic devices. | Yu Li Huang Wei Chen Andrew T.S.Wee | 2021 | SmartMat2021，2，2： | 4 |
| 4 | Surface molecular doping of all-inorganic perovskite using zethrenes molecules显示文摘We present an optical and photoelectron spectroscopic study to elucidate the interfacial electronic properties of organic-inorganic semiconductor heterojunctions formed in a kinetically blocked heptazethrene triisopropylsilyl ethynylene (HZ-TIPS) and its homologue,octazethrene (OZ-TIPS) on an all-inorganic perovskite cesium lead bromide (CsPbBr3) surface.The photoluminescence behavior of the underlying perovskites upon differing molecular doping conditions was examined.It turns out that the charge transfer dynamics of thermally-evaporated OZ-TIPS molecule exhibited a faster average lifetime than that of the HZ-TIPS case suggesting the importance of the biradical state in the former molecule.An interfacial dipole was formed at the interface due to the competing interaction between the dispersion force of the bulky TIPS-substituent group and the attractive van der Waals interaction at the first few layers.Photoemission spectroscopy of the physisorbed HZ-TIPS shows chemical shifts,which indicates electron transfer from HZ-TIPS molecules to the CsPbBr3 perovskite single crystal.In contrast,the adsorbed OZ-TIPS molecular layer on CsPbBr3 demonstrates the opposite trend indicating a hole transfer process.The average molecular orientation as determined by near edge X-ray absorption fine structure (NEXAFS) suggests that the HZ-TIPS molecular plane is generally lifted with respect to the perovskite surface.We suggest that the nature of the closed-shell electronic ground state of HZ-TIPS could contribute to the formation of interfacial dipole at the molecule/perovskite interface. | Arramel Hu Pan Aozhen Xie Songyan Hou Xinmao Yin Chi Sin Tang Nguyen T.Hoa Muhammad D.Birowosuto Hong Wang Cuong Dang Andrivo Rusydi Andrew T.S.Wee Jishan Wu | 2019 | Nano Research2019，12，1： | 1 |
