This article investigates the effect of aluminum doping on the thermal conductivity and other thermoelectric properties of nanostructured Zn1•XAlXTe (0 ≤ X ≤ 0.15) for a temperature range of 300 K – 600 K. The thermal conductivity was measured using the transient plane source (TPS) technique by a thermal constants analyzer. It was found that with increasing doping of aluminum, the thermal conductivity decreased, and with increasing temperature thermal conductivity also decreased. The decreasing of thermal ...
Thermal conductivity is one of the most important properties of fuel and cladding material. In this study, the thermal conductivity of uranium and T91 steel were measured using the transient plane source (TPS) method. Results showed that the thermal conductivity of T91 increased gradually to a point, then decreased. Fast reacting cladding materials require high thermal conductivities, and T91 was found to have higher conductivities than other commercial materials. As ...
The transient plane source (TPS) method is a popular technique that is used to measure the thermal properties of solids. The TPS method is widely used because it can test a variety of materials, it is easy to set up, and measurements are non-invasive. A downside of the TPS method is that it requires two homogenous samples, unlike invasive contact-probe techniques. This study proposes the idea of a “stamp sensor”, ...
As electronic devices approach nanometer scales, heat distribution becomes nonuniform and hot spots begin to form. Integrating graphene into nanoelectronics enhances thermal conductivity and heat flow which mitigates hot spots. In this experiment, large quantities of graphene were produced and thermal conductivity was measured by the transient plane source (TPS) method using an instrument. Results showed that the addition of graphene greatly improved the thermal conductivity of the thermal interface ...
This work introduces a specifically designed sensor to measure the thermal conductivity of thin, insulating materials. This sensor, referred to as the hot square sensor, is unlike the standard sensors, in the sense that it is square in nature, and does not have two, thin layers of Kapton insulation on either side of the thin, metal heating spiral. The lack of Kapton allows a good thermal contact between the sample ...
