Bi2SeTe2
Bi2SeTe2 is a topological insulator vdW layered crystal. It has the same crystal structure as Bi2Se3 and Bi2Te3, it only differs in that Se and Te atoms are alloyed to retain impressive topological insulator state rivaling to Bi2Te3. Bi2SeTe3 crystal composition can be written as Bi2Se3(x)Te3(1-x) where x=1/3. Bi2SeTe2 crystals have been synthesized using three (3) different methods, chemical vapor transport (CVT), flux zone growth, and Bridgman technique. Owing to its high crystallinity and high purity we strongly recommend flux zone or Bridgman growth methods as a synthesis choice. Our crystals measure world record <1cm in lateral sizes, they are perfectly oriented along 0001 direction, and are ready for exfoliation. Crystals are stable in air thus no special storage advised.

Nb2SiTe4
Nb2SiTe4 is a layered narrow gap semiconductor. It crystallizes in monoclinic phase (P121/c1) wherein Nb and Si cations are sandwiched between Te anion atoms forming the individual layers. Nb2SiTe4 crystals are all perfectly layered and easy to exfoliate much similar to MoS2 and Bi2Te3 crystals. Overall it exhibits 0.4 eV optical band gap which has important applications towards mind-infrared and infrared technologies. Our Nb2SiTe4 crystals have been synthesized through chemical vapor transport (CVT) technique at high purity limits (99.9995% or higher) to ensure crystals are environmentally stable and optical/electronic grade. Each order comes with couple mm sized crystals as shown in the product images.

SiTe2
SiTe2 is a new layered crystal produced by 2Dsemiconductors using conventional chemical vapor transport technique (CVT) at 99,9995% purity rating. SiTe2 currently remains largely unexplored and many exciting properties are awaiting to be discovered. Early theoretical predictions show that they exhibit unique thermal conduction and electronic transport properties.Currently, each order contains one single crystal that measures a few mm in size (~3-4mm) due to its hard growth characteristics.

FePSe3
FePSe3 is a layered van der Waals (vdW) crystal, and it has been predicted to have an Ising-type antiferromagnetic ordering from bulk to the monolayer limit. FePSe3 is a semiconductor with an optical band gap of 1.3 eV in the bulk limit, while its monolayer band gap value is an on-going research in the field. Another open question remains as to if the Neel temperature depends on the material thickness and the number of layers. Our FePSe3 crystals were grown using flux zone growth technique to produce FePSe3 crystals without any phase separation. Thus, we guarantee that FePSe3 crystals will have no FeSe, FeP, or FeSe2 minority phases, but the crystal is 100% single phase FePSe3 with proven 99.9999% purity rate which is ideal for magnetism, electronics, and optical measurements.

MnPSe3
MnPSe3 is a 2D Heisenberg-type magnetic material with Neel temperature at 77K [1] MnPSe3 crystals have been synthesized through chemical vapor transport (CVT) or flux transport technique (similar to CVT except chemical transport agent is not utilized to attain high crystallinity and purity) with confirmed 99.999% purity and high crystallinity. Each crystal measures few mm in size, and one order includes 3 pieces of MnPSe3 crystals. MnPSe3 flakes are perfectly oriented along 0001 (c-axis) direction. To date, MnPSe3 has been mostly studied in the bulk form. It has antiferromagnetic response but undergoes antiferromagnetic to ferromagnetic transition (AFM to FM) at low temperatures. More recently, MnPSe3 sheets have also been demonstrated to be an efficient photocatalytic and electrocatalytic material.All these products are handled using non-magnetic tweezers and in non-magnetic environment with tools that are free of magnetic impurities to ensure intrinsic magnetic properties can be confidently measured and probed.

ZrTe3
Zirconium tritelluride (ZrTe3) is a semimetal exhibiting charge density wave (CDW) at around 60-70K and superconducting phenomena (Tc~2-5K). It belongs to the group-IV transition metal trichalcogenides. Our crystals have been engineered to attain rather low record defect density (1E9-1E10cm-2) to yield environmentally stable ZrTe3 crystals. Please see Raman spectrum in this document; CVT grown crystals age in air rather quickly whereas flux grown crystals exhibit their true Raman signatures. In fact, Te defects are well-known cause for environmental degradation effects as well as reduced material quality and performace.
ZrTe3 crystals exhibit semimetallic behavior with charge density waves (CDW) phenomena at temperatures below ~70K. Material undergoes superconducting transition at ~2.7K in bulk but it is anticipated to have larger Tc for mono- and few-layers depending on the substrate monolayer interaction. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Our crystals come with guaranteed CDW behavior and stability.¥ 0.00

BiInTe3
BiInTe3 layered crystals crystallize in M2X3 structure where M stands for Bi and In atoms at fixed 50% alloy ratios. BiInTe3 crystals were synthesized using modified Bridgman technique under careful growth condition to ensure there is no phase separation into Bi2Te3 and In2Te3. Despite their predicted topological properties, their experimental properties remain largely unknown. Each order contains around 3-5mm sized crystals that are ready for exfoliation with superior environmental stability.
