have a final in a few hours and this was a great refresher. quick, concise, and accurate! Thanks

Your first method to show the [-1 0 2] direction in hexagonal system is not correct. You should use Miller-Bravais conversion to calculate t in [UVTW] coordination system. That is the reason you did not achieve the same vector from your second method.

Thanks man. Nice visualization!

One question: You do not need to use equations like U=2/3(2u-v) to transform from 3-axis to 4-axis?

So what's the method in your mind, could you please explain?

yeah i think he needs to use these equations to convert the indices to 4 axis indices

Thank U Mr.David

Really helpful thanks a lot:)

Very helpful, thanks mate.

Thanks. It is helpful.

heloo sir it was very helpful and i can solve many questions by watching this video thanks a lot

in this case our a2 is 0 but if it is not zero then how we take the perpendicular of respective position in order to draw direction in HCP?

Thanks now I understand

Hello. I have a question. I would like to calculate an h, k, l values for hexagonal InN. Coud you please help me with it? I already calculated d(hkl)=0.270 nm. Now I would like to calculate "a" and "c". But for this I need h, k, l..

so nice i like it,

Thanks

liifffeee saaaaveerrrrrr!!!!

Plz make more on hexagonal planes

Can someone here help me to draw 2020 and 1010 hcp planes ? Thank you for your help

David I need to contact with you how.

You made a mistake in HCP, when you apply （-1/2 0 1/2) , you should draw two lines parallel to a1 and a3 axis which are 1/2a long, not perpendicular, than connect them together

thow lines shouldn't be perpendicular but parallel

I don't trust this. For one, he only converted t (a3) in the Miller-Bravais conversion. You also need to convert u (a1) and v (a2). w = W (Z). Secondly, he combined a cubic coordinate system with a hexagonal one. You CANNOT simply draw a perpendicular line to find where the vector goes. You have to use a hexagonal coordinate system. Nicely drawn out, good presentation, but bad information.
