However, a value known as the "sheet resistivity", which depends on both the resistivity and the thickness, can be readily measured for the top surface n-type layer. For a uniformly doped layer, the sheet resistivity is defined as: $$rho_{square}=frac{rho}{t}$$ where ρ is the resistivity of the layer; and t is the thickness of the layer.
