Tellurium has two-dimensional phases and some Weyl nodes around its Femi level that make it a suitable candidate for the study and application in nonlinear optics. Here the authors show the synthesis and use of bio-grown optical Te(0) nanoparticles for optical modulation and thermo-optic switching.
