silicon has several properties that make it preferable to germanium, the main ones being:
- higher junction temperature of operation without damage, 150C vs. only 60C
- silicon dioxide is a stable insulator making passivation, inexpensive plastic packages, and monolithic ICs possible vs. germanium oxide is a powdery water soluble solid requiring expensive hermetically sealed metal or glass packages
- silicon is more abundant than germanium on the earth

Which of the two semiconductor material Si or Ge has larger conductivity at room temperature?
Ge has higher conductivity than Si. Because at room temperature the electron and hole mobility for Ge is larger than those of Si. Another explanation is the lower band gap of Ge than Si.
Why Si is used than Ge in semiconductor diode?
silicon diodes Cut in voltage is 0.7 V.but the Germanium cut in voltage is 0.3 V that's why .............
What is cut in or knee voltage of Si and Ge?
For Si it is 0.6or 0.7 and for Ge 0.3 or 0.2.Both values correct for both si and ge
Why Ge and Si is not used for making LEDs?
Ge and si are not used for Making led's because these two emitts less amount in form of light and larger amount in form of heat.
What is cut in voltage of LED?
cut in vge si .6&ge 0.2

Which is p-type impurities?
all metal which have 3 electron in valance band mixed in the pure semiconductor (like Ge,Si) are called p-type impurities
What is cut in or knee voltage of Si and Ge?
For Si it is 0.6or 0.7 and for Ge 0.3 or 0.2.Both values correct for both si and ge
Which has higher leakage current-Si or Ge?
Ge
Which atom is most metallic in character Mg Si Ge or I?
Mg. I is a non-metal and Si and Ge are metalloids.
What are the difference between Ge and Si diode?
the energy required to break covalent bond in si is 1.1ev and in ge is 0.7ev
What is the cut in voltage of GE and SI diodes?
for germanium it is 0.3 and for silicon it is 0.7
What is the threshold voltage of silicon and germanium?
In semiconductor uses, such as diodes and transistors, the forward voltage drop for Silicon (Si) is a little less than 0.7 volts, while the FVD for Germanium (Ge) is about 0.3 volts.
How do you spell greg in Chinese?
格雷格(ge lei si )or 格瑞格(ge rui si)
Why si is better than ge?
1.Bandgap is comparatively large hence suitable for low & high temp. 2.High melting point of si makes it stable over wide temp. 3.si is more freely available in nature. 4.leakage current less than ge.
Why silicon is better semiconductor material than germanium?
The advantages of Si over Ge are: => Stable and strong material & crystal structure like diamond => Si has a wider bandgap than Ge => higher operating temperature (125-175 oC vs. ~85 oC) and thus become intrinsic at higher temp. => Si readily forms a native oxide (SiO2) high-quality insulator protects and "passivates" underlying circuitry helps in patterning useful for dopant masking. =>Large variety of process steps possible without the problem of decomposition (as in the case of compound semiconductors) => Si is cheap and abundant
