Question 2: а. Find the conductivity of an intrinsic semiconductor which have the following values: µe = (0 + 0.25) m²/V.s; µp = (0+ 0.035) m²/V.s; n¡ = (0 + 1.55) × 10*m³.

what would happen if we replaced the PVC rod with a semiconductor material? What mechanisms could we employ to inject energy into the bound charges in the semiconductor to force it to act like more of a conductor?

Describe an extrinsic semiconductor material. What is the value or the electron concentration in an n-type material, and what is the value of the hole concentration in a p-type material?  

Question 1 |Soalan 1] (a) Semiconductor materials have gradually replaced vacuum tubes in most of such applications, due to many of their favourable properties such as small size, light weight, low energy consumption, high frequency capability, and high reliability. [Bahan semikonduktor secara beransur-ansur menggantikan tiub vakum dalam kebanyakan aplikasi, kerana banyak sifat yang menguntungkan mereka seperti saiz kecil, ringan, penggunaan tenaga yang rendah, keupayaan frekuensi tinggi, dan kebolehpercayaan yang tinggi.] (i) Discuss the fundamental differences between conductor and insulator in term of electron and conduction of current. [Bincangkan perbezaan asas antara konduktor dan penebat dalam istilah elektron dan pengalihan arus.] (ii) Discuss how the conductivity in pure semiconductors varies with temperature. [Bincangkan bagaimana konduktiviti dalam semikonduktor tulen berubah dengan suhu.] (iii) Compare the depletion region in forward bias and reverse bias. [Bandingkan…

A p-type semiconductor joined to an n-type semiconductor ... Pick those that apply. Will not allow current to flow in either direction. Has electron current flowing from the n-type to the p-type material Allows positive current flow from the p-type to the n-type material Allows current to flow in only one direction, and blocks the flow in the other direction Makes a diode
