Two-dimensional (2D) non-van der Waals (vdW) transition metal carbides and nitrides (TMCs and TMNs) have emerged as new members of the 2D materials family with various applications. Their high conductivity and excellent chemical inertness are promising in electrical applications, especially when combined with other 2D semiconductors. Here, this dissertation will mainly focus on developing synthesis methods for 2D non-vdW TMCs and TMNs, investigating their crystal and domain structures, and exploring their application as conductive electrodes in 2D electronic devices. A series of synthesis methods for 2D non-vdW TMCs and TMNs will be demonstrated, including liquid metal growth, chemical conversion, and plasma-assisted conversion. Polarized Raman spectroscopy and electron microscopy are applied to investigate the domain structures and formation mechanisms of 2D non-vdW TMCs and TMNs, as well as their heterostructures. Electrical properties are examined for 2D non-vdW TMCs and TMNs and their heterostructures, showcasing their application as electrode materials in 2D electronics.
