Why germanium semiconductor is used in hall effect experiment not silicon?
germanium low sensitivity
What has the highest index of refraction?
Diamond (2.33)is far from the highest. The highest are silicon and germanium. Silicon has a refractive index of 3.96 and germanium has the highest with 4.01.
Is germanium a good conductor of electricity?
Germanium is a good conductor because it is between silicon and tin, its a metalloid. Tin can conduct electricity and so can germanium
The Maximum spectral response of the germanium and silicon is in the?
Ultraviolent rays
Maximum spectral response of the germanium and silicon?
Visible region
Why silicon does not emit light?
I agree with Binitha on the point that Silicon is an indirect band gap semiconductor.
Why germanium is not used as LED material?
LEDs are made from binary semiconductors (e.g. gallium aluminum indium phosphide) not unary semiconductors (e.g. silicon, germanium) because they can be made transparent to light. Silicon & germanium are opaque.
Where is germanium and silicon located in computer chips?
Germanium is not used in integrated circuits. Silicon is.
Can you give examples of elements that are metalloids?
The metalloids are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium.
What element is used in making transistors and chips?
Silicon and Germanium are the elements used in transistors
What has more shells or rings germanium or silicon?
germanium
Is silicon a semiconductor?
Yes,silicon and germanium are semiconductors.
Why ordinary silicon diodes do not emit light?
Silicon is opaque to all light (IR through UV).The bandgap of silicon is not high enough to produce visible photons, only IR photons.
Why germanium is better than silicon?
products made by silicon are more stable than those made by germanium
Why leakage current of germanium is more than silicon?
Because the space charge region or depletion region is small in germanium compared to silicon hence leakage current is more in germanium than silicon
What is the most familiar semiconductor?
silicon and germanium
Why is silicon a better semiconductor than germanium?
Silicon is a good semi conductor than germanium because silicon is more readily available, cheaper and stable.
