van Ginkel, H.J. (author), Mitterhuber, Lisa (author), van de Putte, Marijn Willem (author), Huijben, Mark (author), Vollebregt, S. (author), Zhang, Kouchi (author)Reducing the thermal conductivity of thermoelectric materials has been a field of intense research to improve the efficiency of thermoelectric devices. One approach is to create a nanostructured thermoelectric material that has a low thermal conductivity due to its high number of grain boundaries or voids, which scatter phonons. Here, we present...journal article 2023
