Thermal (Kapitza) resistance of interfaces in compositional dependent ZnO-In2O3 superlattices

Thermal conductivity and thermal boundary resistance of nanostructures

: We present a fabrication process of low-cost superlattices and simulations related with the heat dissipation on them. The influence of the interfacial roughness on the thermal conductivity of semiconductor/semiconductor superlattices was studied by equilibrium and non-equilibrium molecular dynamics and on the Kapitza resistance of superlattice's interfaces by equilibrium molecular dynamics. T...

Kapitza resistance and the thermal conductivity of amorphous superlattices

Relation between thermolectric properties and phase equilibria in the ZnO–In2O3 binary system

The electrical conductivities, Seebeck coefficients and thermal conductivities across the ZnO–In2O3 binary system are reported and related to the phase compositions and microstructures present at 1150 and 1250 C. The ZnO–In2O3 binary system is of particular interest as it contains a variety of different types of phases, superlattice (modular) phases, solid solutions, two-phase regions and cryst...

Molecular Dynamics Prediction of the Thermal Resistance of Solid-solid Interfaces in Superlattices

Molecular dynamics simulations are used to predict the thermal resistance of solid-solid interfaces in crystalline superlattices using a new Green-Kubo formula. The materials on both sides of the interfaces studied are modeled with the LennardJones potential and are only differentiated by their masses. To obtain the interface thermal resistance, a correlation length in the bulk materials is fir...

The Effects of Nano In2O3 and ZnO on the CO Gas Detection of the SnO2 Sensor

The pellet-type SnO2 sensor was synthesized by the solid state method and the effects of additives such as nano ZnO (1-12 mol %) and nano In2O3 (1-10 mol %) on the CO gas sensitivity of sensor were investigated. The optimum sintering temperature was chosen 800°C because of the porosity content of the samples. The phase analysis and microstructure of the samples were studied by x-ray diffraction...
