Any dataset here, as the library's Tabulated material (znte/marple-1964).

# ... load znte as above, then:

res = ls.solve(sim)  # exact Mie for a sphere
print(res.q_ext)     # extinction efficiency at each wavelength

Same spec runs with DDA, FDTD, BEM or T-matrix: ls.compare(sim, ["mie", "dda"]).

About ZnTe (Zinc telluride)

Zinc telluride (ZnTe) is a binary II-VI semiconductor compound with a direct bandgap that makes it attractive for several optoelectronic applications. It has a cubic crystal structure and is known for its photoluminescent properties. ZnTe is particularly important in the development of semiconductor devices for terahertz frequencies. It is also utilized as a buffer layer in some solar cell configurations, especially in tandem with cadmium telluride (CdTe). Moreover, its ability to form alloyed compounds with other II-VI semiconductors, like CdTe, allows for the tuning of optical properties for specific applications. The compound is also studied for potential use in blue and green light-emitting diodes and laser diodes.
