Abstract:

Ruddlesden–Popper (RP) lead halide perovskites have emerged as a new class of tunable two-dimensional semiconductors that demonstrate high performance in optoelectronics. The nanostructured RP perovskites such as nanowire are the basic building blocks for manufacturing high-density integration of circuitries and devices. However, the practical realization of nanostructured RP perovskites is challenging due to their complex organic−inorganic layered crystal structures. Some nanofabrication methods such as template growth, lithography, inkjet printing and chemical vapor deposition have been used to obtain RP perovskites nanostructure which are still limited to in-plane and low-resolution. In this talk, I will discuss my research progress on the development of 3D printing for fabricating freestanding Ruddlesden–Popper perovskites nanowires with controlled diameter and length. I expect this work to pave the new way for integration of Ruddlesden–Popper perovskites nanowires in optoelectronic integrated circuits.
