Do Aden Belle stay together?
yes they do 0k
Do electronics work better in the heat or cold?
Electronics built on current technology typically works best at low temperatures. For certain applications, very low temperatures (even as low as 0K) are ideal, as conductivity increases and approaches superconductivity at this temperature. Superconductivity means no loss of energy in heat, and allows for certain electronic devices to operate much more efficiently and potentially faster than at higher temperatures. However, today's practical electronics are not designed for operation at very low temperature. Some electronic components, such as some forms of resistors or capacitors will fail at low temperatures. Other components, including the solder, wires, the circuit board and all mechanical parts including connectors would become fragile, brittle, or otherwise struggle. Today's electronics are normally rated for operation in a 0..70C temperature range (commercial grade), -40..+85C (industrial grade) and -55..+125 (military grade). For a rule of thumb and for today's practical electronics, "room temperature" is a good operating temperature regardless of theoretical advantages of superconductivity.
Why semiconductor acts as an insulator at 0K?
Because at this temperature the covalent bond become stronger which can't be broken by applying external forces(voltage).
What is the number of free electrons and holes in a pure semiconductor at 0k?
There are no free electrons and holes in a pure semiconductor at 0k.
Why pure semiconductor just behave like an insulator?
At absolute zero (0K), an intrinsic semiconductor will act like a perfect insulator. At this temperature, the electrons in the valence band will remain there. The heat energy required to excite the electrons from the valence band to the conduction band is insufficient at 0K. When the temperature increases, some of the electrons from the valence band got excited and moves to the conduction band. This will give rise to the conductivity of the semiconductor. i.e in 0 k(0 kelvin) the pure semi conductor the electrons in the valance band don't do any thing.They are lazy for conductivity.But when increasing the temperature increase the energy of electrons and they try to move.At the end electrons win and they can to move.So it happened a conductivity.
How do you get super weapons on robot rage?
0k i win rules 0k
Does nothing get colder then 0k on the kelvin scale?
no
If it is 0 Kelvin what is the temperature in celsius?
0K = -273.15ºC
How did summerian obtain food?
0000 not gud this 0k
Do Aden Belle stay together?
yes they do 0k
How cold is zero kelvin in fahrenheit?
0K = -459.67ºF
Fahrenheit absolut zero?
0K = -273.15oC = -459.67oF
What degrees Celsius equals 0 Kelvin?
0K = -273.15ºC
Why fermi energy level is midway between conduction band and valence band in semiconductors?
To be exact EF should be at the valence band edge (EV) at 0K because no energy state above EV are occupied at 0K; however, for intrinsic semiconductors there are no states in the band gap anyway, so placing the EF anywhere in the band gap including conduction band edge does not add any states as being occupied. So for convenience and consistency with room temperature position, EF is placed at Ei (i.e. room temperature intrinsic Fermi level position).
