Types of Semiconductors

Types of Semiconductors

Intrinsic semiconductors are highly pure materials with no impurities. At absolute zero, these semiconductors behave as perfect insulators because all the valence electrons are bound, and the conduction band is empty, disallowing electrical conduction. The Fermi level is a concept used to describe the probability of occupancy of energy levels by electrons at thermal equilibrium. In intrinsic semiconductors, the Fermi level is positioned at the midpoint of the energy gap at absolute zero. When...

Gravity between Spherical Bodies

Gravity between Spherical Bodies

Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...

Background:

Lunar permanently shadowed regions (PSRs) are extremely cold environments, ideal for sensitive experiments.
PSRs offer proximity to solar power and potential resources, making them crucial for future lunar missions.

Purpose of the Study:

To propose the deployment of a passive, ultrastable optical resonator in lunar PSRs.
To leverage the unique lunar environment for advanced laser systems with unprecedented phase-coherence.

Main Methods:

Utilizing the cryogenic conditions of lunar PSRs to construct a monolithic silicon cavity.
Achieving ultra-low thermal noise-limited stability and coherence times exceeding 1 minute.

Main Results:
