Presentation Transcript

  1. Laser flashLFA477 MengPei LU

  2. Figure of merit generator Electricity Heat refrigerator Seebeck coefficient Electrical resistivity Thermal conductivity Hall ; four point probe LFA + DSC + Archimedes

  3. LFA447 κ=D × Cp × ρd

  4. Method • Heating by laser pulse • Measure temperature versus time by IR detector

  5. Thermal conductivity • T/Tmax = 0.5 = 1.37 * a p2 t 0.5 /L2

  6. Sample preparation 攜帶物品 手套 鎳子 碳膠(噴膠) 擦拭紙 試片 (方載台, 螺絲起子) (隨身碟, 筆記本, 筆) 行前準備 量厚度 噴雙面碳膠 確認有液態氮

  7. Let’s get to work !
