Title*:	youngs Modulus Question
Question*:	Hi Dear fiends... please answer this question: Is any change in the Young's Modulus, if changing the thickness of a material? Example: if i take two thin layer of GaAs with the thickness of 50nm and 10nm, Both layers are same material with different thickness. Is any change in the Young's Modulus of GaAs.

Youngs modulus is the property of the material. So it will be independent of it's dimensions.
So Youngs modulus will not change with the thickness of a material.

Y =[ force per unit area/(change in length per unit original length)],
so for same material of different thickness, i think "Y" , will not change . it only will differ from one material to another....as already commented before.

* Y (i.e Young's Modulus of steel is greater than rubber..:) )
