Embodiment Construction

[0050] Disclosed herein are TE modules comprising: pairs of sputter-deposited thin-film thermal elements; and conductive components interconnecting the thermal elements in series or in series-parallel. Also disclosed is a TE power device formed from a plurality of TE couples, such as an array of TE couples, wherein the thin film thermal element has a thickness greater than at least about 20 cm -1 Or a L / A ratio greater than about 100 cm-1, with certain embodiments having an L / A ratio greater than 1000, 10,000, or even higher.

[0051] Unless otherwise indicated, all numbers expressing amounts of ingredients, properties such as L and A values, thicknesses, power levels, etc. used in the specification and claims are to be understood as being modified by the term "about", whether explicitly stated or not. Accordingly, unless expressly indicated to the contrary, the numerical parameters set forth are approximations.
