WTe2 solution vial Typical WTe2 crystal used for WTe2 solution production

WTe2 solution

$390.00
This product contains WTe2 flakes (type-II Weyl semimetal) in dispersed isopropanol solution. WTe2 crystals has been synthesized synthetically at 99.9995% purity and they have been dispersed into isopropanol (electronic grade chemical at 99.9999% purity) by ultrasonic treatment. Since the starting material (synthetic WTe2 crystals) is highly crystalline, ultrasonic treatment to delaminate WTe2 layers yields highly crystalline WTe2 mono- and few-layers suspended in isopropanol solution. The crystallinity of WTe2 nanomaterial has been confirmed through electron energy dispersive spectroscopy (EDAX), Raman spectroscopy (FWHM<5 cm-1), and scanning electron microscopy (SEM) measurements. Lateral sizes of WTe2 flakes deposited onto different substrates range from ~10nm - ~10 um while thickness range from 1L to thicker sheets.
Solution type: By default 2Dsemiconductors USA will provide WTe2 sheets suspended in isopropanol owing to good dispersion, stability, and high performance. However, if your research requires other solvents, please contact us for more details and schedule for the product delivery.
Solution concentration:  To reduce shipping costs, easy customs agreement / border check-in processes, we ship supersaturated 2D solutions (~80-120 mg/L depending on the type of 2D layers). However, supersaturated solutions can be diluted to produce ~250-500mL of solution to deposit 2D layers onto desired substrates through simple and cost-effective spin-casting process.
