Abstract: A thermoelectric composite material includes MXene inserted at a boundary of a crystal grain consisting of a thermoelectric material. Accordingly, the thermoelectric composite material may have a reduced thermal conductivity and an increased electrical conductivity. Furthermore, a mechanical property of the thermoelectric composite material may be improved. Thus, the thermoelectric composite material may improve a thermoelectric ability of a thermoelectric module.

Abstract: A capacitor for a semiconductor memory element includes a lower electrode, a dielectric layer disposed on the lower electrode and including titanium oxide, and an upper electrode disposed on the dielectric layer. The lower electrode includes a first metal and a second metal, the first metal including at least one selected from the group consisting of platinum (Pt), osmium (Os), rhodium (Rh) and palladium (Pd), the second metal including at least one selected from the group consisting of ruthenium (Ru) and iridium (Ir).
