AB  - Studying the physics of thin films is the first step towards understanding how ‘quantum’deviceswill be controlled as the plethora of phenomena promised by quantum materials can only be fullyexploited once they can be fabricated as thin films. Meanwhile, there is a growing focus on scalingup the growth of interesting quantum materials to 200–300 mm wafer size using molecular beamepitaxy (MBE), with the aim of integrating these materials into the semiconductor industry [1]. However,much remains to be discovered about growing quantum materials as thin films rather than inbulk and the effect this has on the quantum or topological properties of the materials and their subsequentcontrol. In this review study, we identify systems in which quantum effects are particularlyrelevant when grown in thin film form, highlighting the challenges and initial successes and addressingissues such as feasibility and effort-to-impact ratios. These include: topological insulators, Weylsemimetals, and subsequent topological phase transitions; altermagnets (particularly those that exhibitaltermagnetism only in thin film form); high-temperature superconductors and the emergingphenomena of oxides and nitrides; magnetic spin textures (particularly skyrmions and hopfions);quantum spin liquids and spin ices; and hexagonal perovskites and other 2D materials [2, 3, 4, 5].Our goal is to generate interest in growing new thin-film quantum materials at the JCNS facilitiesand to initiate discussions about implementing these material systems. MBE is clearly at the heart ofa materials revolution and will become an increasingly necessary growth process for furthering thefundamental science of quantum materials, as well as their utility in developing the next generationof devices.Seite[1] ‘Introducing the latest production MBE systems for III-V and nitride materials!’ DCA, (2025) [Online].Available: https://dca.fi/introducing-the-latest-production-mbe-systems-for-iii-v-and-nitridematerials/[2] C.
