Low dimensional materials exhibit astonishing electronic, optoelectronic and mechanical properties due to the small dimension induced quantum or mechanical effect. For this reason, the low-dimensional materials are broadly exploited for fabrications of devices with novel functionalities such as lasers, photodectors, sensors, solar cells, transistors and light-emitting diodes (LEDs). Driven by the significant role of the low dimensional materials, my Ph.D. research has been focused along two directions, i.e., the synthesis of low dimensional materials in addition to fabricating devices with novel functionalities using such materials. Due to the relatively large Bohr radius zero-dimensional (0D) cadmium selenide (CdSe) quantum dots and the ensuing large size range of quantum confinement effects, I report the synthesis of highly crystalline CdSe quantum dots using colloidal chemical method by which the size of the quantum dots can be controlled. We also characterized the ultraviolet–visible spectroscopy and photoluminescence properties of the quantum dots. I synthesized one-dimensional (1D) zinc tin oxide (ZTO) and indium tin oxide (ITO) nanowires using vapor-liquid-solid (VLS) method, and fabricated quantum dot sensitized solar cells (QDSSC) and 2D/1D junctions using such materials. In addition, this method can also be used to fabricate ferromagnetic particles like NiI2 as what will be described in Chapter 2. In Chapter 3, I report an ingenious method based on VLS method to grow individual ITO nanowire on graphene, which is a true 2D/1D junction, and successfully fabricated into a device with the Ohmic nature. This device is essentially completely different from the conventional 2D/1D junction devices in the sense that individual ITO nanowire with flexible orientations is grown on the graphene layer, which directly leads to a continuous interface with atomic crystalline structure. The device provides a new platform to enhance our understanding of the electronic transport properties of the interface of 2D/1D junctions, and our method pushes the limit of controllable synthesis of 1D nanomaterials on arbitrary substrates. We fabricated ITO nanowire/single layer graphene emitter sample and did field emission characterization in nanoscale distance by Scanning tunneling microscope (STM). A high field emission enhancement factor of ITO/ single graphene Ohmic junction has been obtained.
