關(guān)于材料吸收邊和禁帶寬度精確測(cè)量或計(jì)算方法討論 已有1人參與
|
|
1.起初,我們估算材料的吸收邊時(shí),都是對(duì)材料的吸收譜圖做兩條切線,相交做垂線,交于橫軸(波長(zhǎng))得到吸收邊。但第一次投JAC時(shí),審稿人提出如下問題:The absorption edge must be given by another accurate method not by a simple one wich has a large error. 2.修改論文時(shí),我們參照參考文獻(xiàn),依照α = A * (h * ν - Eg) n/2 / hv, 曲線做切線與X軸交點(diǎn)為禁帶寬度。但二審,該審稿人對(duì)此方法有異議,再次提出問題,如下: because the authors did not use an accurate method for detecting the absorption and depend only on the optical density mesurements which gives a large error in determining the optical band gap and did not calculate the experimental error. The authors must be treat this point before accepting the manuscript due to its important in the main characteristic of the nanostructural materials. 3.想請(qǐng)問大家,有什么更加精確的方法可以測(cè)量或者通過這個(gè)吸收譜圖來計(jì)算一個(gè)材料的吸收邊和禁帶寬度。求幫忙解決一下這個(gè)問題! |
