∙ 13y agoThe Energy level of P-type semiconductor is higher than that of N-type semiconductor because the Dopant impurity always creates energy state near the Conduction Band while the Acceptor Impurity always creates energy state near the Valence Band.
Also the answer could be found in the reason that very few electrons gain thermal energy to leap the forbidden energy gap, thus more the electrons more will be the probability of gaining energy and leap to conduction band from valence band and as we know p-type semiconductors have more valence electrons than n-type semiconductors.

Why does an extrinsic semiconductor behave as an intrinsic semiconductor at elevated temperature?
...It is due to the fact that at higher temperatures, the energy in the semiconductor is greater than Eg by a considerable amount, meaning that the conduction band is more full. At these high temperatures, the dopants' role on electron-hole pairs is negligible.
How intrinsic semiconductor can be made into extrinsic semiconductor?
at higher values of temperature the intrinsic carrier concentration become comparable to or greater than doping concentration in extrinsic semiconductors. thus majority and minority carrier concentration increases with increase in temperature and it behaves like intrinsic semiconductor.
Why schottky is called hot carrier diode?
Because the energy of electrons transfer from semiconductor to metal side have more energy than the fermi energy of electrons in metal side. That's why these are called hot carrier diodes
Why is resistivity of a semiconductor higher than that of a metal?
Resistivity is the resistance, in ohms, between the opposite faces of a 1-metre-cube of a material. For metals, resistivity is in the region of 0.0000001 ohm-metre. For semiconductors, it is much higher - it is in the region of 0.01 ohm-metres.
Principle of generator?
Light may be generated in two conditions. a) when a material is heated sufficiently that it glows - so-called black-body radiation, b) when an excited electron; previously raised to a higher energy level than its natural state; is allowed to cool and return to its natural energy level. In this energy shift, it will emit a quantum of light quite specific to the element concerned, and the energy change.
Do gamma rays have a higher or lower energy level than X-rays?
gamma rays have a way stonger/higher energy level then x rays
When an atom has one or more electrons in higher energy levels?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
Which electron in oxygen have the higher energy those in the first energy level or those in the second?
The second level is associated with higher energy than the first is. Keep increasing the energy of an electron enough, and eventually it breaks free of the atom completely.
What happen when an atom has more electrons that can fit in one energy level?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
What is the starting energy in the sun?
The nuclear energy available in the hydrogen. This is a kind of potential energy. Hydrogen has a higher energy level than helium.

2+ oxidation number in the 2nd energy level?
The answer to this question is that the oxidation number for the 2nd energy level is +2. This is because the 2nd energy level is the second highest energy level in an atom, and thus has a higher oxidation number than the 1st energy level. The oxidation number for the 2nd energy level is determined by the number of electrons in the 2nd energy level.
Which electrons in oxygen have more energy those in the first energy level or in the second?
More energy have the electrons in the second level of energy.

How do energy differences between higher energy levels of an atom compare to lower energy levels?
They are smaller in magnitude than those between lower energy levels.
Can you get Pokemon level higher than 100?
No you can not get Pokemon higher than level 100.
What does nuclear energy use to create its source of energy?
From the nuclear forces. An U-235 atom has a higher energy level than its daughter products; this is used in nuclear fission.
