abstract = {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
