Effect of finite heater thickness on 3ω thermal conductivity measurements
نویسندگان
چکیده
The 3ω method is popular for thermal conductivity measurements. It consists of a strip heater above a substrate, and the results are usually based on approximate solutions of the heat conduction equation for simplified heating in which the heater is assumed to be a thin plate. Through numerical studies, it is found that a finite heater thickness has an effect on the value of the thermal conductivity that is obtained from experiments. The effect of a fluid above the heater is also investigated.

Analysis of 3ω method for thermal conductivity measurement
The 3ω method for measurement of thermal conductivity of a solid usually consists of a strip heater above a substrate, and the method is based on an approximate solution of the heat conduction problem in which the heater thickness is neglected. We establish a two-dimensional heat conduction model for the heater-on-substrate 3ω method which takes into account the finite thickness of the heater. ...

The 3ω method is a well established technique for experimentally extracting thermal conductivity of thin films and substrates. The 3ω method calculates thermal conductivity by measuring thin film temperature response to a metal strip heater deposited on the material’s surface. The electrical resistance of the metal strip is used as both heat source and temperature sensor. An important factor in...
متن کاملImproved 3-omega measurement of thermal conductivity in liquid, gases, and powders using a metal-coated optical fiber.
A novel 3ω thermal conductivity measurement technique called metal-coated 3ω is introduced for use with liquids, gases, powders, and aerogels. This technique employs a micron-scale metal-coated glass fiber as a heater/thermometer that is suspended within the sample. Metal-coated 3ω exceeds alternate 3ω based fluid sensing techniques in a number of key metrics enabling rapid measurements of smal...

In this work, we present experimental studies on the cross-plane thermal conductivity of InAs/AlSb superlattices. The thermal conductivities of MBE grown InAs/AlSb superlattices are measured using the 3ω method from 80-300 K. The influence of the growth temperature and post annealing is investigated. Significant reductions in thermal conductivity are observed in these superlattices compared to ...
