晶体照片: Product Description Zirconium ditelluride is a semimetal exhibiting massless Dirac Fermions. ZrTe2 belongs to group-IV TMDCs family and adopts a stable 1T-octahedral structure. ZrTe2's electronic band structure has interesting characteristics showing crossings of valence and conduction bands, near the Fermi level suggesting topological 3D Dirac semimetal behavior [1]. Interestingly, DFT calculations have also shown opening of electronic band gap for sheets below 3-4 layers, and becomes direct gap semiconductor in monolayer form (Egap~0.3-0.5 eV). These ZrTe2 crystals were designed and optimized at our facilities starting 2014 to achieve perfect electronic grade materials with: 1) excellent stoichiometry, 2) large single domain size, 3) single phase materials without any mixed phases or amorphous content, 4) unmatched purity -electronic grade (5.8N), 99.9998% confirmed. Our crystals exhibit sharpest Raman and XRD peaks in the commercial market proving the high quality of our materials.purity. Properties of ZrTe2 layered crystals
