Show that low pressure chemical vapour deposition [low pressure combined with high gas velocity due to pumping] results in surface reaction limited growth.
Homework Answers
Low pressure chemical deposition uses the heat to initiate the reaction on solid substrate, low pressure is used to avoid any unwanted reaction, but continuous deposition cause local increase in concentration which eventually limits the reaction growth, this might be the disadvantage of this process.
