The Maximum spectral response of the germanium and silicon is in the?
The maximum spectral response of germanium is in the infrared region, while the maximum spectral response of silicon is in the visible light region. Germanium has a broader spectral response range compared to silicon.
What parameter in a germanium diode differs from those in a silicon diode?
A germanium diode has a lower forward voltage drop compared to a silicon diode, typically around 0.3V for germanium and 0.7V for silicon. Germanium diodes also have a higher reverse current leakage compared to silicon diodes.
Why germanium has larger leakage current than silicon?
Germanium has a smaller bandgap compared to silicon, leading to higher intrinsic carrier concentration and hence greater leakage current. Additionally, germanium has a higher intrinsic carrier mobility, which can further contribute to increased leakage current compared to silicon.
What is knee voltage for silicon and germanium?
The knee voltage for silicon is approximately 0.7V, while for germanium it is around 0.3V. The knee voltage is the voltage at which a diode starts conducting significantly.
What is the difference of silicon diode and germanium diode?
A silicon diode has a voltage drop of approximately 0.7V, while a germanium diode has a voltage drop of approximately 0.3V. Though germanium diodes are better in the area of forward voltage drop, silicon diodes are cheaper to produce and have higher breakdown voltages and current capabilities.
The Maximum spectral response of the germanium and silicon is in the?
The maximum spectral response of germanium is in the infrared region, while the maximum spectral response of silicon is in the visible light region. Germanium has a broader spectral response range compared to silicon.
Why silicon does not emit light?
I agree with Binitha on the point that Silicon is an indirect band gap semiconductor.
Where is germanium and silicon located in computer chips?
Germanium is not used in integrated circuits. Silicon is.
What element is used in making transistors and chips?
Silicon and Germanium are the elements used in transistors
The modern name for eka-silicon?
germanium
What has more shells or rings germanium or silicon?
germanium
Is silicon a semiconductor?
Yes,silicon and germanium are semiconductors.
Why si and ge does not emit light?
Silicon (Si) and Germanium (Ge) do not emit light because they are indirect bandgap materials. This means that when they are excited, most of the electrons and holes recombine through phonon-mediated transitions, resulting in the release of heat instead of light. In contrast, direct bandgap materials, such as gallium arsenide (GaAs), release light when electrons and holes recombine.
Can you give examples of elements that are metalloids?
The metalloids are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium.
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.
What is the most familiar semiconductor?
silicon and germanium
What are pure semiconductors?
silicon and germanium
