      abstract     = {Thermoelectric oxides can provide the advantage of
                      high-temperature stability in oxygen-containing atmospheres.
                      It is known that the incorporation of multiwalled carbon
                      nanotubes (mw-CNT) can change the thermoelectric as well as
                      the structural properties of oxides. Here, we report the
                      influence of mw-CNT on the thermoelectric properties of
                      Al-doped ZnO (AZO). The preparation of the mw-CNT-added AZO
                      was done using an ultrasonic mixing of the starting
                      materials followed by a spark plasma sintering process under
                      vacuum. The Seebeck coefficient S, thermal conductivity λ
                      and electrical conductivity σ were determined in the
                      temperature range between 300 K and 900 K. It was observed
                      that the thermal conductivity is significantly reduced by
                      the incorporation of the mw-CNT. At the same time, the
                      electrical conductivity is increased by a factor of 21 from
                      8700 S/m to 190,000 S/m. The Power factor PF=S2σ indicates
                      that the addition of mw-CNT improves the thermoelectric
                      properties of Al doped ZnO in comparison to the reference
                      sample prepared with same process but without mw-CNT},
