詳細介紹
Bismuth Telluride (Bi?Te?) Developed at our facilities since early 2013 to optimize the perfect stoichiometry and stabilize the topological insulator state.Topological insulator is a new class of material, in which its bulk is insulating while its surface states are conducting. The surface states of topological insulator are robust against any external perturbation because such states are protected by time-reversal symmetry. Similar to transition metal dichalgonides and graphite, Bi?Te? is also layered material with weak interlayer coupling. Our crystals are develop in our laboratories in last two years and are highly crystalline. Raman spectrum displays very sharp and clear modes at 102 cm-1 and 134cm-1 with FWHM less than 4cm-1. If your research needs doping in Bi2Te3, we can also incorporate Ca, Nb, Ni, and Au dopants in Bi2Te3 crystals. Please also see our Tl alloyed Bi2Te3 crystals to advance your topological insulator studies.
