Germanium (Ge) is a metalloid that can behave as a semiconductor when used in electronic devices. It has properties that allow it to conduct electricity under certain conditions, making it suitable for use in semiconductor applications. Copper (A), silver (B), and aluminium (C) are not typically used as semiconductors.
So, the correct answer is option (D): Germanium.
Assuming in forward bias condition there is a voltage drop of \(0.7\) V across a silicon diode, the current through diode \(D_1\) in the circuit shown is ________ mA. (Assume all diodes in the given circuit are identical) 


From the following, how many compounds contain at least one secondary alcohol? 
Semiconductors are a crystalline solid materials, whose electrical conductivity lies between a conductor and an insulator. Semiconductors are mainly used in the manufacturing of electronic devices like capacitors, transistors, diodes, Integrated circuits, etc.
