研究领域

研究方向 凝聚态与材料物理专业。横跨材料学、物理学和化学。研究方向主要是先进材料(新颖低维度电子材料,如超导材料、电池材料、功能材料、磁性材料等)的生长,材料的物性测量(使用X-ray,neutronscattering,PPMS,SQUID,quantumdilatometry等)、材料的物性调控与核磁共振研究,和与之相关的高压强、低温、强磁场等极端环境高科技术的应用与开发等。重点在新颖低维度强关联先进固体材料的物性调控与核磁共振研究。

研究内容 1)采用PLD(pulsedlaserdeposition)、temperaturegradientflux、vaportransport、solidstatesynthesis等实验技术(按需要选择),生长实验用高质量的单晶、多晶或薄膜材料。 2)利用X-ray或neutronscattering对所生长出的材料的结构和成分进行分析,以保障生长出高纯度的合格材料。 3)利用PPMS,SQUID等对合格材料的基本电性(电阻、磁阻)、磁性(磁化率)和热性能(比热)进行测量。 4)进行核磁共振(NMR)实验研究(重点之一)。在原子尺度上(atomicscale)直接观察导电电子的电荷、自旋的静态和动态行为。比如,可以对超导材料的电子配对方式,低维度强关联电子材料可能会显现的CDW(charge-densitywave)、SDW(spin-densitywave)、及超导、金属-非金属、磁性等各类相变现象的发生等,提供直接的原子尺度上的证据与观测,并有能力可以进行各种相变类型的判别。进而揭示出其各自发生的可能机制,并可直接验证理论工作者提出的各种有价值的物理学理论的有效性与否(若有必要验证),如超导理论、Luttingerliquid理论等。 5)进行物性调控实验(重点之二)。众所周知,材料的物性大都由电子的行为决定,而电子的行为是可以调控的。调控电子的方式很多。除采用可改变基本的化学元素或摻杂元素量的多少外,这里主要是采用高压强、极低温、强磁场等极端环境技术,并可综合以上提到的一些实验技术(高端应用)。此项实验除可揭示出材料的调控机理外,还会揭示电子的量子基态,会有新的重要发现。根据需要,可以随时和国内或国际的相关研究团体合作共同进行一些需要的实验测量。 承担的科研项目 1)SynthesisoftheElectron-dopedHighTemperatureSuperconductorsandtheuseofX-RayPowderDiffraction,首席(PI),SCAgrant,2011–2012,UniversityofWestFlorida 2)DevelopmentofaHighResolutionACSusceptometerforACMagneticSusceptibilityMeasurementsasa FunctionofTemperatureforMaterialResearchandScienceEducation,首席(PI),SCAgrant,2010–2011,UniversityofWestFlorida 3)Growthandcharacterizationoftheelectron-dopedhightemperaturesuperconductors,首席(PI),SCAgrant,2011–2012,UniversityofWestFlorida 4)CAREER:SynthesisandInvestigationofNovelCondensedMatterCompoundsandDevelopmentofa High-ResolutionCapacitiveDilatometer,参与[首席(PI)为:JohnJ.Neumeier(FloridaAtlanticUni.)],美国国家自然科学基金项目(NSFGrant#DMR-9982834)2000–2004 5)Growthandphysicalpropertiesmeasurementsofnovelcondensedmattermaterials,参与[首席(PI)为:JohnJ.Neumeier(MontanaStateUni.)],美国国家自然科学基金项目(NSFGrant#DMR-09070362009–2014 6)NMRStudiesofDensityWavePhases,Superconductivity,andPolymerElectronicConduction,参与[首席(PI)W.G.Clark(Uni.ofCalifornia,LosAngeles(UCLA))],美国国家自然科学基金项目(NSFGrant#DMR-0072524)2000–2003 7)US-IndiaCooperativeResearch:SpinandChargeDynamicsinConductingPolymersbyNuclearMagneticResonanceStudies,参与[首席(PI)W.G.Clark(Uni.ofCalifornia,LosAngeles(UCLA)],美国国家自然科学基金项目(NSFGrant#DMR-0225578)2002–2006 8)NMRInvestigationofDensityWaves,Organicconductors,Superconductors,andConductingPolymers,参与[首席(PI)W.G.Clark(Uni.ofCalifornia,LosAngeles(UCLA)],美国国家自然科学基金项目(NSFGrant#DMR-0334869)2003–2008
