A dopant, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) to alter the electrical or optical properties of the substance. In the case of crystalline substances, the atoms of the dopant very commonly take the place of elements that were in the crystal lattice of the base material. The crystalline materials are frequently either crystals of a semiconductor such as silicon and germanium for use in solid-state electronics, or transparent crystals for use in the production of various laser types; however, in some cases of the latter, noncrystalline substances such as glass can also be doped with impurities.
The addition of a dopant to a semiconductor, known as doping, has the effect of shifting the Fermi levels within the material. This results in a material with predominantly negative (n-type) or positive (p-type) charge carriers depending on the dopant variety. Pure semiconductors that have been altered by the presence of dopants are known as extrinsic semiconductors [See: intrinsic semiconductor]. Dopants are introduced into semiconductors in a variety of techniques: solid sources, gases, spin on liquid, and ion implanting. See ion implantation, surface diffusion, and solid sources footnote.
The Dopants(ドーパント,Dōpanto) are the fictional antagonists in the Kamen Rider SeriesKamen Rider W. Dopants are normal humans who use Gaia Memories. The Gaia Memories are aspects of the true Gaia Memory(地球の記憶,Chikyū no Kioku), the knowledge of everything on the Earth. These were originally accessed due to Philip's link to the Gaia Memory by means of the Gaia Library(地球（ほし）の本棚,Hoshi no Hondana). But after he was taken from them, the Sonozaki Family uses a strange temple underneath their mansion to access the Gaia Memory. They then sell these to the highest bidder or to common criminals, both types used as guinea pigs to study the Gaia Memories as part of the Gaia Impact project. The name comes from the English words "dopant" and "doping".
Open the book And I saw an angel come down from heaven Having the key of the bottomless pit And a great chain in his hand I laid whole on the dragon, That old serpent Which is the Devil, and Satan, and born in a thousand years I'm the soldier type, keep grip on steel like Conan Money bulgin' out my pockets, I peel with both hands Inter-national dopeman, known as a D-Boy If ya need me nigga, know you can call on the decoy Me, All I do is move blow off tha corner Paper chasin', cause I'm tryin to stack doe like colma, (Watch me) I'm tryin' to keep my head on tight Baller blockers make a nigga wanna ride at night Block watchers callin' coppers so my mind ain't right The Devil with me but the young boy acknowledge Christ I did alot of ridin' in my time, and God blessed me still I look out for tha one the knocks So why the Devil keep on fuckin' with me, why Why he knockin' at my door, my door Why the Devil keep on fuckin' with me Can you tell me why he huntin' me for Tell me what he huntin' me for, tell me Could you tell me Could you tell me what he huntin' me for Tell me what he huntin' me for Could you tell me, tell me Could you tell me what he huntin' me for You thinkin' lifes a joke, I'll slice your throat Oh you a thug, you about to get yo' rights revoked I'm from the Dirty, we don't even know the price of soap I'm a star, look in the sky, you need a microscope I'm way ahead of the game, thuggin' runs in my veins My pockets chubby, so I went and got a gun in my name Its just me, him and my blunt in the Range A young nigga with the filty slang Ha ha, I hop out like a Jack In The Box With three macks and a glock I'm askin' for nothin', I'm snatchin' my props I'm gettin' money while I'm laughin' at cops It ain't ya lad, I ain't bad It's the Devil, why don't you tell'em to stop Its like somebodys lookin' over my shoulder Its hard to focus in the open I'm surrounded by vultures So many haters I don't know where to turn And niggaz be starin' us down like we got money to burn First things first, I'm sick of all you industry thugs You feel me, You a enemy if anything cuz In memory of Death to the powers that be See I'm a motherfuckin' soldier ain't no coward in me Somebody is constanly watching and following me Throw shades over my eyes, Wont allow me to see Allow me to peek Forget about reading the fine print My lyrical content on some Vietnam shit Shoot 99% dogg, top of the line I'm back on my grind Satan in the back of my mind Go a-head with the bullshit, tomorrow ain't promised I'm pushin' the rock to stop from getting knocked unconscious Though I walk through the valley of the shadow of death I will fear no evil, for thou walk with me It's Bad Boy baby, we done seen the ups and downs Sunny days, rainy days, we'll never stop Da Band, the next generation, God first And we won't stop, Yea, Lets go Yea, get off me, get off me You know what team I'm on One God, One love, One family, Bad Boy I'm like Micheal baby Dark Angel, Yea, You feel me I see all you Devils out there You'll never stop us Da Band, 2003, The next generation
