Despite significant research efforts in these areas, achieving reliable and controllable growth of high-quality Bi thin-film allotropes has remained a challenge. Previous studies have reported the growth of trigonal and orthorhombic phases on various substrates yielding low-quality epilayers characterized by surface morphology. In this study, we present a systematic growth investigation enabling the high-quality growth of Bi epilayers on Bi-terminated Si (111) 1×1 surfaces using molecular beam epitaxy. Our work yields a phase map that demonstrates the realization of trigonal, orthorhombic, and pseudocubic thin-film allotropes of Bi. In-depth characterization through X-ray diffraction (XRD) techniques and scanning transmission electron microscopy (STEM) analysis provides a comprehensive understanding of phase-segregation, phase-stability, phase-transformation, and phase-dependent thickness limitations in various Bi thin-film allotropes. Our study provides recipes for the realization of high-quality Bi thin films with desired phases, offering opportunities for the scalable refinement of Bi into quantum and neuromorphic devices and for revisiting technological proposals of this versatile material platform from the past 30 years.ASCII FilesCC0 WaiverPhase-Selective Epitaxy of Trigonal and Orthorhombic Bismuth Thin Films on Si (111)Figure 10-A.dattext/x-fixed-fieldFigure 10-B.dattext/x-fixed-fieldFigure 10-C.dattext/x-fixed-fieldFigure 10-D.dattext/x-fixed-fieldFigure 10-E.dattext/x-fixed-fieldFigure 10-F.dattext/x-fixed-fieldFigure 10-G.dattext/x-fixed-fieldFigure 10-H.dattext/x-fixed-fieldFigure 10-I.dattext/x-fixed-fieldFigure 11-A.dattext/x-fixed-fieldFigure 11-B.dattext/x-fixed-fieldFigure 11-C.dattext/x-fixed-fieldFigure 11-D.dattext/x-fixed-fieldFigure 11-E.dattext/x-fixed-fieldFigure 11-F.dattext/x-fixed-fieldFigure 11-G.dattext/x-fixed-fieldFigure 11-H.dattext/x-fixed-fieldFigure 11-I.dattext/x-fixed-fieldFigure 11-J.dattext/x-fixed-fieldFigure 11-K.dattext/x-fixed-fieldFigure 2.dattext/x-fixed-fieldFigure 3-A.dattext/x-fixed-fieldFigure 3-B.dattext/x-fixed-fieldFigure 3-C.dattext/x-fixed-fieldFigure 3-D.dattext/x-fixed-fieldFigure 3-E.dattext/x-fixed-fieldFigure 4-A.dattext/x-fixed-fieldFigure 4-B.dattext/x-fixed-fieldFigure 4-C.dattext/x-fixed-fieldFigure 4-D.dattext/x-fixed-fieldFigure 4-E.dattext/x-fixed-fieldFigure 4-F.dattext/x-fixed-fieldFigure 6-A.dattext/x-fixed-fieldFigure 6-B.dattext/x-fixed-fieldFigure 6-C.dattext/x-fixed-fieldFigure 7-A.dattext/x-fixed-fieldFigure 7-B.dattext/x-fixed-fieldFigure 7-C.dattext/x-fixed-fieldFigure 7-D.dattext/x-fixed-fieldFigure 7-E.dattext/x-fixed-fieldFigure 7-F.dattext/x-fixed-fieldFigure 7-G.dattext/x-fixed-fieldFigure 7-H.dattext/x-fixed-fieldFigure 7-I.dattext/x-fixed-fieldFigure 8-A.dattext/x-fixed-fieldFigure 8-B.dattext/x-fixed-fieldFigure 8-C.dattext/x-fixed-fieldFigure 8-D.dattext/x-fixed-fieldFigure 8-E.dattext/x-fixed-fieldFigure 8-F.dattext/x-fixed-fieldFigure 8-G.dattext/x-fixed-fieldFigure 8-H.dattext/x-fixed-field
