P. -O. Chapuis, S. Kumar Saha, S. Volz

摘要:

在谐波3w模式下增加扫描热显微镜(SThM)灵敏度的一种方式是用足够高的AC电流加热探针,以在AC和DC信号之间产生耦合。在本文中,我们详细介绍了如何正确地考虑到这种耦合与Wollaston探针SThM。我们还展示了如何正确地链接到SThM测量的热导率的热导率。

英文摘要:

A way to increase the Scanning Thermal Microscope (SThM) sensitivity in the harmonic 3w mode is to heat the probe with an AC current sufficiently high to generate a coupling between the AC and the DC signals. We detail in this paper how to properly take into account this coupling with a Wollaston-probe SThM. We also show how to link correctly the thermal conductivity to the thermal conductance measured by the SThM.
