  Strained trigonal Te has been predicted to host Weyl nodes supported by a
non-symmorphic chiral symmetry. Using low-pressure physical vapor deposition,
we systematically explored the growth of trigonal Te nanowires with naturally
occurring strain caused by curvature of the wires. Raman spectra and high
mobility electronic transport attest to the highly crystalline nature of the
wires. Comparison of Raman spectra for both straight and curved nanowires
indicates a breathing mode that is significantly broader and shifted in
frequency for the curved wires. Strain induced by curvature during growth
therefore may provide a simple pathway to investigate topological phases in
trigonal Te.
