Web對 4 邊方形端頭而言,長度 (l) 是指從測量面到安裝面的距離。5 邊立方體和圓盤則是到前表面的距離。 刀具可設定的公差範圍,取決於測針端頭相對於機器軸的平面度和平行度。 必須對所有測頭和測頭固定座進行微調,才可達成這些設定。 范德堡法(英語:Van der Pauw method),又稱四點量測法,是一種測量樣品電阻率和霍爾係數的技術。它能夠用於精確測量任意形狀的樣品,只要樣品大約是二維的(非常薄),固體(無孔),電極能放在它的邊上。范德堡法在樣品四周放置了四個探針,這與四端點測量技術不同:前者測得樣品平均電阻率,而後 … See more 使用這種技術有五個必須滿足的條件: 1. 樣品必須是具有均勻厚度的平面形狀。 2. 樣品必須沒有任何孤立的洞; 3. 樣本必須是均勻和各向同性的; See more 使用范德堡法時,樣品厚度必須遠低於樣品的寬度和長度。為了減少計算的誤差,樣品最好是對稱的。樣品必須沒有孤立的洞。 測量時需放置四個歐姆接觸。他們的位置需要滿足一定條件: • 它們必須在樣品的邊界(或儘可能接近邊界)。 See more 遷移率 半導體材料的電阻率可以由以下公式得到: $${\displaystyle \rho ={\frac {1}{q(n\mu _{n}+p\mu _{p})}}}$$ 其中,n和p分別是 … See more • 電極在左上開始按逆時針從1到4編號。 • 電流I12是由1流入由2流出的直流電流,單位是安培(A)。 See more 樣品的平均電阻率ρ=RS⋅t,薄層電阻RS的決定如下。對於電阻率各向異性材料、個別電阻組件,如ρx或ρy,可以使用蒙哥馬利方法計算。 基本的測量 See more 1. ^ Koon, D.
