Analysis of heat flow in layered structures for time-domain thermoreflectance

Cahill, David G.·2004·Review of Scientific Instruments

Abstract

The iterative algorithm of Feldman for heat flow in layered structures is solved in cylindrical coordinates for surface heating and temperature measurement by Gaussian-shaped laser beams. This solution for the frequency-domain temperature response is then used to model the lock-in amplifier signals acquired in time-domain thermoreflectance measurements of thermal properties.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Over the past two decades, TDTR has emerged and evolved as a reliable, powerful, and versatile technique to measure thermal properties of a wide range of bulk and thin film materials and their interfaces.

    “Over the past two decades, ultrafast laser-based time-domain thermoreflectance (TDTR) has emerged and evolved as a reliable, powerful, and versatile technique to measure the thermal properties of a wide range of bulk and thin film materials and their interfaces.”
  • Using the phase signal for data reduction has the advantage over the amplitude signal that it does not require normalization.

    “Using the phase signal for data reduction has the advantage over the amplitude signal as it does not require normalization. 22”
  • The key advance in the data analysis of TDTR experiments was made by Cahill in 2004, solving the three-dimensional heat diffusion equation through multi-layered structures with consideration of the pulse accumulation effect.

    “The key advance in the data analysis of TDTR experiments was made by Cahill in 2004. 22 The three-dimensional heat diffusion equation through multi-layered structures was solved with the consideration of the so-called 'pulse accumulation' effect”
  • The transient thermoreflectance technique can be implemented as both the TDTR method and the frequency-domain thermoreflectance (FDTR) method.

    “The transient thermoreflectance technique can be implemented as both the TDTR method 22, 24, 25 and the frequency-domain thermoreflectance (FDTR) method 93, 94 (see Section III(A) for more details of FDTR).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
