Preface This volume is the compilation of the accepted proceedings which were submitted to the 12th European Conference on Silicon Carbide and Related Materials 2018 (ECSCRM 2018) held in Birmingham, UK from 2nd - 6th September.
ECSCRM, alongside its sister conference ICSCRM, provides a vibrant scientific forum in which recent issues relating to silicon carbide and other wide bandgap materials, including gallium nitride, gallium oxide and graphene, can be discussed.
These contributions spanned the wide range of topics being worked on in the field of SiC and related semiconductor materials.
