l二维材料垂直异质结高性能光电器件研究通过一种可控的CVD外延生长法制备垂直堆叠的MoS2/MoSe2范德华尔斯异质结,异质结上原子排布均匀、界面无合金化。通过顶层MoS2单层改善异质结中载流子传输过程,与单层MoS2器件相比,异质结迁移率提升6倍,同时,得益于内建电场,电荷实现有效分离,抑制载流子复合,获得高达36A/W的响应率以及4.8×1011 Jones的高通断比。该工作丰富了二维范德华尔斯异质结的材料体系,加速了低维半导体研究领域向系统集成的发展。Nano Research, 2020

l二维材料垂直异质结的普适性生长机理与可控生长研究。在化学气相沉积生长中,通过在调控生长源的组分配比,并引入低熔点的盐类化合物,在低生长温度(600-700)实现水平和垂直异质结的可控生长。研究发现在高的W/Se前驱体比例浓度时,多种前驱体的形成能相似,共同参与生长成核,但是W1Se1前驱体分子在底层材料MoS2表面的扩散势能较大,优先被保留在底层材料表面成核生长,最终促进异质结的生长。该生长机理与技术已成功验证并适用于多种异质结材料。Advanced Materials, 2019, Highlight: 研之成理

l超构材料中超旋电磁场调控二硫化钼(MoS2)谷荧光发射。由纳米棒结构的周期组合和排列形成了C4对称超材料表面,二维材料被夹在金属层和超表面之间的电介质层中。超构材料在左/右旋圆偏振光激发下,呈现不同的近场超旋电磁场模式。由于材料激子与超旋电磁场共振耦合作用不同。左旋圆偏振光激发下,二硫化钼的谷偏振度从25%增强到43%,右旋光圆偏振激发时,二硫化钼的谷偏振度从25%降低到20%。该工作实现了手性超构材料对二维材料谷激子荧光效率的调控作用,突破材料自身非各向异性限制,实现了手性的谷极化度探测。同时,弱化了谷极化荧光的激发条件,首次利用线偏振光成功观测到谷极化荧光现象。(Advanced Materials, 2018

l利用光的自旋与轨道耦合调控激子-等离激元耦合过程。通过加工纳米尺度的金属螺旋结构,利用光在结构中产生的自旋轨道耦合的机理,可以实现光操控激子-等离激元耦合增强。在金属结构的增强作用下,左旋光激发时单层MoS2信号增强超过10倍,在右旋光激发时信号未显著增强。系统研究发现,该耦合过程与纳米结构的尺寸参数、螺旋结构圈数、激光的功率和激发波长密切相关。利用Majorana球模型首次分析了纳米结构中的光的自旋与轨道耦合现象。并利用该原理实现了旋光操控的发光阵列,左旋光和右旋光分别呈现“PKU”字母的明文和暗文发光。(ACS Nano, 2017, Highlight: ACS Nano:'In Nano', Design for Science, ESI High Cited Paper <1%)

l氮化硼材料中谷的赝自旋研究。氮化硼(BN)及碳原子掺杂氮化硼(BCN)材料体系在缺失C3对称性的保护情况下,材料仍具有非等价的能谷和完美的谷赝自旋性质,并且材料的带隙可随碳原子掺杂浓度从紫外到远红外大范围可调。低浓度的掺杂下,由于人工超结构和谷的相互作用,能带劈裂城分裂的能级并具有非连续的谷霍尔电导。在高浓度掺杂下,实验上在可见光波段观察到由于谷极化导致的圆极化的光致发光现象,室温下发出的圆偏振光的极化率接近40%,77k低温时,极化率高达70%。(Nano Letters, 2017)

l石墨烯量子点/二硫化钼复合材料的电荷转移过程研究。石墨烯量子点 (GQDs)与单层二硫化钼(MoS2)相互作用会在复合材料界面处发生电荷转移过程。控制石墨烯量子点在二硫化钼上的覆盖密度,通过对二硫化钼的荧光峰位和发光波长进行分析与观测,发现2纳米的量子点在非饱和浓度时对二硫化钼电子掺杂更有效。 通过激子发光三能级模型,分析了材料中激子和三激子的竞争激励,从荧光峰强度估算电子掺杂的浓度(Advanced Materials, 2015)

l等离激元热电子调控单层二硫化钼的光学性质。光激发金属纳米颗粒产生表面等离激元共振,在共振的衰减过程中,会产生大量的热电子可以实现光控的电子掺杂效应。在掺杂的过程中,单层MoS2的吸收光谱和荧光光谱都发生显著的变化,该变化与金属颗粒的形貌尺寸、激发光波长、强度等密切相关;Drude模型可以从光谱变化间接估算电子掺杂浓度。利用热电子掺杂效应,实现了基于二维材料的光控光器件。(ACS Nano, 2015)
