摘要: A raw material gas is supplied to a space in which a silicon carbide seed crystal is placed. A silicon carbide single crystal is grown on the seed crystal by keeping a monosilane partial pressure at 4 kPa or more and heating the space to a temperature of 2400° C. to 2700° C. The temperature of the space and supply of the raw material gas are controlled such that a temperature gradient of a growth crystal surface of the silicon carbide single crystal in a radial direction is 0.1° C./mm or less, and a radius of curvature of the growth crystal surface is 4.5 m or more, thereby producing a silicon carbide single crystal ingot having a growth length of 3 mm or more and an internal stress of 10 MPa or less. The ingot is then cut into a silicon carbide single crystal wafer.

摘要: The present invention provides an optical ZnS material and a preparation method thereof, wherein the preparation method comprises: charging zinc and sulfur into a first crucible and a feeding device of a chemical vapor deposition furnace, respectively; heating the first crucible, the second crucible and a deposition chamber, and charging sulfur into the second crucible through the feeding device; introducing an inert carrier gas into the first crucible, and introducing an inert carrier gas and hydrogen into the second crucible, flowing the carrier gas containing zinc vapor and sulfur vapor respectively into the deposition chamber through pipelines to deposit ZnS, and supplying the second crucible with sulfur regularly and quantitatively through the feeding device during the deposition process to maintain a saturated vapor pressure of sulfur in a range of 0.8 to 1.8 KPa. The preparation method of the present invention does not generate H2S; thus it can avoid the formation of hydrogen-zinc complexes by H ions produced from the decomposition of H2S and Zn vapor, which would otherwise affect the transmittance and emissivity of ZnS material.

摘要: The exemplary embodiments describe techniques for a controlled chemical vapor deposition growth and transfer of arrayed TMD monolayers on predetermined locations, which enable the formation of single crystalline TMD monolayer arrays on specific locations. The unique growth process includes the patterning of transition metal oxide (e.g., MoO3) on the source substrate contacting the growth substrate face-to-face, where the growth of single crystalline TMD monolayers with controlled size and location, exclusively on predetermined locations on the growth substrates is accomplished. These TMD arrays can be align-transferred using a unique process that combines the wet and stamping transfer processes onto any target substrate with a pin-point accuracy, which dramatically enhances the integrity of transferred TMDs.
