Electron.
The definition of a conductor (electrical as opposed to music or trains) is a material that easily allows the movement of charges and in most cases, that is a metal and the charges are electrons. One can, however, have ionic fluids and the movement of positive ions as part of the conductivity, but that doesn't start with the letter e.
Particle.
Silver is a good conductor that begins with the letter "s".
insulator
Countries beginning and ending with the letter A are:AlgeriaArgentinaAlbaniaAndorraArmeniaAustraliaAustria
As. The shortest word beginning with the letter a is "a"
semiconductors are the conducors they are partially conduct electricity. And we can increase therir conductivity by using various method . They are Intrinsic method and extrinsic method . Intrinsic method is heating the semiconducter . Extrinsic method is doping. By using this method the conductivity of semiconductors is rapidly increases. Then we use semiconductors are prefferd to conductors

Lambda is the eleventh letter of the Greek alphabet. It is a particle in subatomic particle physics. It can also indicate the wavelength of a wave.
An 'insulator' is something that does not conduct electricity.
