The significant improvement might be caused by the Cu substrate which has higher thermal conductivity than conventional Sapphire substrate. However, Cu substrate is a ductile metal plate and easy to deform during the processing. The deformation of the Cu substrate will destroy the LEDs that were bonded on the Cu substrate. Finally, LEDs will be fabricated on the patterned Cu/Si substrate to make high-power LEDs and solve the deformation problem in processing.

The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.
