What are GaN and AlN Templates Used For?

 

A researcher has informed us of his current template use:

I am currently growing some 2D transition metal dichalcogenides (2d TMDC) based semiconductors on III Nitride templates such as GaN and AlN. My goal is to study if there is some clear epitaxial growth between these two different materials.

While we have got some promising results for growth on GaN, we are still studying what happens when we try to grow on AlN. So that's why there is some delay on placing the orders. Once we have established that the 2D materials can be grown on onto these semiconductors, then i will go forward with the orders. I also see that u have graphene on SiO2/Si that also another substrate that i am keen on exploring with regards to 2D TMDC.

LED Epitaxy Grown on GaN

Rsearcher asks:

You dont by chance have LED epitaxy grown on GaN wafers do you? Something with blue epitaxy already grown that is?

UniversityWafer RFQ#253397 Response:

GaN-on-GaN 2” blue LED wafers. the whole substrate is Gallium Nitride. Blue wavelength 445~465nm

Gallium Nitride (GaN) Templates

GaN templates, AlN templates are both available. Researchers use the templates to grow 2D transition metal dichalcogenides and measure their electrical properties. The templates are highly insulating with negligible electrical mobilities. This prevents spurious electrical signal to the 2D materials on surface.

For semi insulating GaN templates, the typical specifications are as follows. Size = 2", Single crystal/highly epitaxial grown on cAl2O3, single side polished, resistivity > or ~ 10^6 ohm cm. Quantity = 1-2 pieces. (based on price per piece). Please tell me if Gallium polar or Nitrogen polar can be obtained.
For semi insulating AlN templates, the typical specifications are as follows. Size = 2", Single crystal/highly epitaxial grown on cAl2O3, single side polished. resistivity > 1 x 10^6 ohm cm. Quantity = 1-2 pieces. (based on price per piece). Please tell me if Aluminium polar or Nitrogen polar can be obtained.
For hBN, the typical specifications are as follows. Size = 10 mm x 10 mm pieces on SiO2/Si. Resistivity > 1 x 10^6 ohm cm. Quantity = 5-10 pieces (based on price per piece).
