4 A prototype Peltier thermoelectric cooling unit has been constructed to cool a cold finger on an 5 electron microprobe. The Peltier unit was tested at 15W and 96W, achieving cold finger 6 temperatures of -10°C and -27°C respectively. The Peltier unit did not adversely affect the analytical 7 stability of the instrument. Heat conduction between the Peltier unit mounted outside the vacuum 8 and...
The work described here is an investigation of thermoelectric phenomena in bipolar semiconductors and p-n junctions. In contrast to majority-carrier semiconductors in which a constant material-dependent Peltier coefficient is defined for a given temperature, bipolar devices can be modeled by introducing a bias-dependent Peltier coefficient at interfaces that takes into account the variation of ...
A gas of interacting ultracold fermions can be tuned into a strongly interacting regime using a Feshbach resonance. Here we theoretically study quasiparticle transport in a system of two reservoirs of interacting ultracold fermions on the BCS side of the BCS-BEC crossover coupled weakly via a tunnel junction. Using the generalized BCS theory we calculate the time evolution of the system that is...
We describe the measurement and modeling of lock-in thermograms of crystalline silicon on glass (CSG) thin film silicon solar modules for a range of bias voltages. For that purpose, a voltage series of lock-in thermograms for a single cell in the module is measured and compared to the area heat production distribution resulting from a Spice electronics simulation. The point spread function for ...
