What are the Characteristics of Direct and indirect band gap semiconductors?
Direct band semconductors are mostly for LEDs. Indirect band semiconductors like Si and Ge are conventional diodes.
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 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.
What is cut in voltage of LED?
cut in vge si .6&ge 0.2
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 .............
Ge and Si are used in making semi-conductors Are these two elements in the same group or the same period?
Ge and Si are in the same group
What are the Characteristics of Direct and indirect band gap semiconductors?
Direct band semconductors are mostly for LEDs. Indirect band semiconductors like Si and Ge are conventional diodes.
What element is used in making transistors and chips?
Silicon and Germanium are the elements used in transistors
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.
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.
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
How do you spell greg in Chinese?
格雷格(ge lei si )or 格瑞格(ge rui si)
Mention cut-in-voltage for Si and Ge diode?
0.6-0.7 V for Si at room temp. and 0.3 for Ge at room temp.
What are the ratings and certificates for Si ge 32A he yi ge xiang jiao shao nian - 1996?
Si ge 32A he yi ge xiang jiao shao nian - 1996 is rated/received certificates of: Hong Kong:IIB
