This dissertation explores the synthesis and transport properties of 2D transition metal carbides known as MXenes, focusing on their potential applications in electronics and energy storage. MXenes are derived from selective etching of the A layers in MAX phases, resulting in conductive carbide cores with surface terminations that affect their electronic properties. The study presents methods to produce epitaxial thin films of MXenes, which are more suitable for electronic applications compared to earlier flake forms. It examines the metallic nature and transport mechanisms of various MXenes, highlighting differences in conductivity and electronic behavior when altering transition metals. The research also introduces novel methods for creating vacancy-ordered MXenes, expanding their potential utility in catalysis and energy storage. Intended for researchers and professionals in materials science, this work contributes to the understanding and development of advanced 2D materials with unique electronic properties.

This dissertation by Chung-Chuan Lai explores the phase formation and crystal growth of nanolaminated transition metal carbide thin films, focusing on their unique properties that combine metals and ceramics. The study investigates the synthesis of thin-film materials, particularly in the Mo-Ga-C and Zr-Al-C systems, revealing new phases such as Mo2Ga2C and optimizing the deposition process of Zr2Al3C4. The research also delves into selective substitution reactions, replacing Al and Ga with Au in nanolaminated carbides, resulting in new layered phases. The findings contribute to understanding the properties and potential applications of these materials in protective coatings, electrical contacts, and nuclear environments. The work is aimed at researchers in materials science and thin-film physics.

This book presents a systematic description of the electronic and physico-chemical properties of transition-metal carbides and nitrides. This is the first book devoted to the theoretical modelling of refractory carbides and nitrides and alloys based on them. It makes use of computational methods to calculate their spectroscopic, electric, magnetic, superconducting, thermodynamical and mechanical properties. Calculated results on the electronic band structure of ideal binary transition metal carbides and nitrides are presented, and the influence of crystal lattice defects, vacancies and impurities are studied in detail. Data available on chemical bonding and the properties of multi-component carbide- and nitride-based alloys, as well as their surface electronic structure, are described and compared with those of bulk crystals.
