Abstract
A method for applying at least one layer, selected from diffusion barriers, further protective layers, adhesion promoters, solders and electrical contacts, onto thermoelectric materials, is characterized by the fact that the at least one layer is rolled or pressed onto the thermoelectric material at a temperature at which the thermoelectric material is flowable.
Claims20
A method for applying at least one diffusion barrier and at least one layer selected from a further protective layer, an adhesion promoter, a solder, and an electrical contact, simultaneously onto a thermoelectric material in one work process, the method comprising:
- rolling or pressing the diffusion barrier and the at least one layer onto the thermoelectric material at a temperature at which the thermoelectric material is malleable, to form a thermoelectric material sandwich,
- wherein thin films comprising material of the diffusion barrier and material of the at least one layer are placed onto the thermoelectric material prior to the rolling or pressing.
