The continuous development of electronics has been characterized by Moore's law. Although the current CMOS integrated circuit development is driven by a lot of innovations, there are still some limits determined by unavoidable physical effects. There are many new ideas for building atomic or molecular scale devices for the information technology, but there is still a gap between CMOS technology and novel devices. The recently proposed thermal-electronic device (phonsistor) and the CMOS compatible thermal-electronic logic circuit (TELC) may help to fill this gap. The operation is based on the semiconductor-metal transition (SMT) effect shown by certain materials, for example VO2. The switches can be excited by electronic and thermal signals as well, thus two different physical parameters are available for representing the logic states. A proof of concept for the device operation has been demonstrated, and device scaling and integration issues will be discussed too.
