ホール効果についてなのですが、磁場から受ける力と電場から受ける力がつり合うと電子は画像のy軸方向に動くのですか？ 教えてください🙏

AZ IC まる。 きさ f = evB〔N〕 のローレンツ力を軸 このため、面Qは負に,面Pは正に帯電し,x軸の正の向きに電界が生じる。 Step② 時間が経過した後 x軸方向の電界の強さをE[V/m] とすると,自由電子は電界の向きと 反対に大きさ F=eE〔N〕の力を受ける。やがて, ローレンツ力と電界か ら受ける力がつり合う (evB=eE) と, 自由電子はy軸方向に直進するよ うになり,面Pと面Qとの間に一定の電位差 V〔V〕 が生じる。 よって 電 位差Vは,次式で表される。 I V=Ed=vBd= endh y enh I また,式(20) より B= V である。 金属に比べて半導体はnが小さいの で, V〔V〕が大きくなって測定しやす く, 磁束密度の測定に利用されている。 (a) (b) V 面P 図 22 ホール効果 B xBd= 面Q IB enh (20) 面P 7 面Q + + Check <Check V=Ed (p.23 式 (10)) I=enSv(p.45 式 (2)) BOMFeE + S=dh V 'f=evB BA + E E + 高 V 1.E 20
