I have three questions regarding the material Gallium Oxide. I was reading in several articles and they introduced its structure as it has monoclinic structure and it consists tetrahedral and octahedral structures in it. What I can't understand I can connect this structure to the chemical...

Thank you all for the answers, it directed me and explained a lot of things to me. :) Sure if I have further questions so I will post it here ;)

Hello Everyone! I read about the function of the ruby laser which made from ruby crystal and has three energy levels. There is radiationless transition to what so called metastable level and then the electrons there stimulated to transit to ground energy state. The question is: does this...

I still here :) thank you so much for answering the thread :)

The link is really useful thank you :)

Thank you so much for the answer :) , yes I'm talking about crystals and nothing biological :D Then the coalescence which process it describes?

Im bit confused about what is exactly the difference between the terms, which process every term describes ?

Why J-aggregation has red shift and H-aggregation has blue shift what is the physics behind it? And the second question is does J-aggregate can makes with another J-aggregate H-aggregate?? (I'm new in this topic)

Thank you for the answer :)

How the number of the particles in a solution increase the probability to get adsorption on a surface? which physical terms explain this? For example when I increase the concentration of molecules in a solution I can see that the adsorption and the aggregation on the surface happen.

How a high mobility of particles over surface cause to aggregation, the professor in the class said that "high mobility causes to local equilibration and thus to a compact aggregation".. which I didn't understand..! What does he mean about local equilibration and how all connect to each other?!

It is a solvent which contains MnTPP molecules and the solution is toluene (the "liquid" that was mentioned above)... yes it is thin fiber embedded in a glass so it is in the same plane with the surface of the glass... the molecules (MnTPP) aggregated over the fiber (the thin fiber)... (The...

I poured a droplet that has 1.55 refractive index (RF) over a fiber that has core and cladding with (RI) 1.45 and 1.4 respectively, and I the molecules aggregated over the fiber, known that because the refractive index of the liquid is higher than of than of the core or the cladding a leakage of...

Yes I mean about the transverse Gaussain modes... when I look at the answers I see ##e^{-\frac{x^2+y^2}{w_0}}\times F(x,y)## where ##F(x,y)## can be bessel or Hermite... So my question is: can one look at this as the Gaussian divided in the space (yellow in the image above), or every mode by...

I saw the solution of the light propagates in cylinder.. so in every solution there is the first order Gaussain function (the slandered one) times another function which gives I think the separation, both of them gives the intensity separation.. So what does that mean?! is it as I draw on the...
