Semiconductor
A semiconductor is a material with an electrical conductivity that is intermediate between that of an insulator and a conductor. A semiconductor behaves as an insulator at very low temperature, and ... > more -
Photoelectric effect
The photoelectric effect is the emission of electrons from matter upon the absorption of electromagnetic radiation, such as ultraviolet radiation or x-rays. Upon exposing a metallic surface to ... > more -
Teleportation
Teleportation, or teletransportation, is the alleged process of moving objects from one place to another more or less instantaneously, without using conventional transportation. With present ... > more -
Electrical conduction
Electrical conduction is the movement of electrically charged particles through a transmission medium. The movement can form an electric current in response to an electric field. The underlying ... > more -
Nanoparticle
A nanoparticle (or nanopowder or nanocluster or nanocrystal) is a microscopic particle with at least one dimension less than 100 nm. Nanoparticle research is currently an area of intense scientific ... > more -
Resonance (chemistry)
Resonance in chemistry is a tool used (predominately in organic chemistry) to represent certain types of molecular structures. Resonance is a key component of valence bond theory and arises when no ... > more
