General Questions and Answers / question on transmission coefficient

« on: July 16, 2009, 23:17 »

hi, I have one question due to the transmission coefficient. My result of transmission coefficient of a two-probe system shows that the coefficient value can be larger than 1 at some energy levels. Although it says that T(k)>1 if several channels contribute to the transport at the same energy. However, based on the physical meaning (or definition) , this value should be always between o and 1.
Anyone can help me to understand this better? Thank you very much.
