As correctly pointed out by Dr Weisbecker, you are usually dealing with few
layers.
Depending on the route used to produce the sample (e.g. Hummers method),
you could have epoxy and hydroxyl groups decorating sheets and causing the
interlayer separation (associated to 00l reflections) to dramatical
Most graphene samples have got few layers thus you can see some broad and weak
00l peaks.However the main part of the diagram is made of asymetric hk bands
(10 11), no hkl reflexions with l non 0 (Have a look at the old papers of
Warren and Franklin):

I think graphene is only one layer so you should only see 00l reflections.
It's a 2 dimensional problem. But I have no actual experience with it (other
than listening to people talk abo
