Reversible thermoelectric nanomaterials
T. E. Humphrey, H. Linke
Irreversible effects in thermoelectric materials limit their efficiency and economy for applications in power generation and refrigeration. While electron transport is unavoidably…
Inhomogeneously doped thermoelectric nanomaterials
T. E. Humphrey, H. Linke
Inhomogeneously doped thermoelectric nanomaterials with a delta-function electronic density of states can operate with Carnot efficiency in the absence of phonon heat leaks. Here w…
Quantum, cyclic and particle-exchange heat engines
T. E. Humphrey, H. Linke
Differences between the thermodynamic behavior of the three-level amplifier (a quantum heat engine based on a thermally pumped laser) and the classical Carnot cycle are usually att…
Optimizing the performance of thermionic devices using energy filtering
T. E. Humphrey, H. Linke
Conventional thermionic power generators and refrigerators utilize a barrier in the direction of transport to selectively transmit high-energy electrons. Here we show that the ener…
