Answer:
option A
Explanation:
correct answer is option A
metalloids are the substances which are not metal and also are not non-metal they have the property of both metals and non-metals.
metalloids example are silicon, Germanium, Arsenic (As) etc.
Usage of metalloids as semiconductor has decreases the size of the circuits which leads to the shrink the size of many electronic devices such as TV, mobile etc.
Answer:
Option (A) Electronic devices have become smaller.
Explanation:
Semiconductor devices are the devices which are based on the properties of the semiconductor materials like germanium, silicon, gallium and arsenide. The commonly used materials in electronic devices are the silicon and germanium because of their low cut off voltages i.e 0.7 v and 0.3 v. Semiconductor materials made the electronic devices smaller as they replaced the Vacuum tubes which was bulky with high operating voltage, high power consumption.
