论文摘要
将散装金属的尺寸缩小到纳米级，导致电子能级的离散性，即所谓的库博间隙。具有可调型和尺寸依赖性的kubo间隙的电子性质重新归一化，使光子发射和电子隧道引人入胜。与通常的三维金属簇相反，在这里我们证明，可以通过二维（2D）金属过渡金属二甲酸酯（即1T'-phase Mote2）纳米簇嵌入半导体polymph（i.e.e.e.e.，1h-------------------------------- i.e.e.e.e.，1h-------------------这样的1T'-1H MOTE2纳米域类似于在2D空间中挤压的3D金属液滴，该液滴显示出强大的极化灾难，同时保持其键完整性，而传统的Delta Gappaper 3D群集则不存在。主机2D MOTE2的较弱筛选导致这种伪金属系统的光子发射，并在1T'-1H-1T'同型中注射载体的弹道注射，这些载体可能会在传感器和2D可重新配置的设备中找到应用。
Shrinking the size of a bulk metal into nanoscale leads to the discreteness of electronic energy levels, the so-called Kubo gap. Renormalization of the electronic properties with a tunable and size-dependent Kubo gap renders fascinating photon emission and electron tunneling. In contrast with usual three-dimensional (3D) metal clusters, here we demonstrate that Kubo gap can be achieved with a two-dimensional (2D) metallic transition metal dichalcogenide (i.e., 1T'-phase MoTe2) nanocluster embedded in a semiconducting polymorph (i.e., 1H-phase MoTe2). Such a 1T'-1H MoTe2 nanodomain resembles a 3D metallic droplet squeezed in a 2D space which shows a strong polarization catastrophe while simultaneously maintains its bond integrity which is absent in traditional delta-gapped 3D clusters. The weak screening of the host 2D MoTe2 leads to photon emission of such pseudo-metallic systems and a ballistic injection of carriers in the 1T'-1H-1T' homojunctions which may find applications in sensors and 2D reconfigurable devices.
