Hello :) , Does anyone know some good paper or book from were it's possible to learn physics behind of work of resonant tunneling diode(RTD)? In last semester I had course in ˝microelectronics and nanoelectronics˝ and we studied basic principle on which RTD works, and it was very interesting to me, so I would like to learn more about it. I asked professor for some additional literature, but I had nothing from there. So if someone have some suggestion, please tell me about it :). Thanks!!
