Long and Medium-Term Research: Transition-Metal Dichal- ompounds

Bonneau Long &amp；中期研究：过渡金属二硫醚；从量子约束到新型包合化合物该奖项是在国外卓越中心长期和中期研究计划下获得的。该计划使美国科学家和工程师能够在国外公认的卓越研究中心进行三到十二个月的研究。该计划的奖励为联合研究提供了机会，并利用独特或互补的设施、专业知识和国外的实验条件。该奖项由加州大学洛杉矶分校的Richard B. Kaner博士赞助，将支持南特大学国家科学研究中心体质与化学研究所的Philippe Bonneau博士和Jean Rouxel博士进行为期12个月的博士后访问研究。他们将研究层状过渡金属二硫化物（TMDs）和其他层状材料，这些材料可以在极性溶剂中剥离或超声产生溶液悬浮单层。然后将悬浮的单层进行大小分离（通过凝胶电泳），用于量子约束研究或与其他低维化合物重新堆叠以创建新的亚稳包合化合物。TMD单层中的量子约束既可以作为粒径的函数，也可以作为单层与各种化学环境相互作用的函数来研究。新的包合物，独特地由低维材料组成，为研究混合低维材料中的插层和电子相互作用、超导性、电荷密度波、以及化学计量学对低维包合物结构和电子性质的影响。奖学金建议提供国际旅行费用和美国本土机构250美元的固定行政津贴。

Bonneau Long & Medium-Term Research: Transition-Metal Dichal- cogenides: From Quantum Confinement to Novel Inclusion Compounds This award is made under the Program for Long- & Medium- Term Research at Foreign Centers of Excellence, which enables U.S. scientists and engineers to conduct three to twelve months abroad at research centers of proven excellence. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. This award, sponsored by Dr. Richard B. Kaner of the University of California, Los Angeles, will support a twelve-month postdoctoral research visit by Dr. Philippe Bonneau with Dr. Jean Rouxel of the Institut de Physique et Chimie des Mat>riaux, Centre Nationale de la Recherche Scientifique, Universit> de Nantes. They will investigate layered transition-metal dichalcogenides (TMDs) and other lamellar materials, which can be exfoliated or sonicated in polar solvents to produce solution-suspended monolayers. The suspended monolayers are then size separated (by gel electrophoresis) and used in quantum confinement studies or restacked with other low-dimensional compounds to create new, metastable inclusion compounds. Quantum confinement in TMD monolayers can be investigated both as a function of particle size and as a function of monolayer interactions with various chemical environments. New inclusion compounds, composed uniquely of low-dimensional materials, provide almost limitless opportunities to study topics such as intercalation and electronic interactions in mixed low-dimensional materials, superconductivity, charge density waves, and the role of stoichiometry on the structure and the electronic properties in low-dimensional inclusion compounds. The award recommendation provides funds to cover international travel and a flat administrative allowance of $250 for the U.S. home institution.
