text: Yo, listen up, let me break it down for you,
  Controlling semiconductors, like silicon, it's true.
  Doping is the game, adding impurities so slight,
  Inorganic electronics, been rocking it since last century, right?
  
  But hold up, there's something new on the scene,
  Doped organic semiconductors, like you've never seen.
  Let me drop the knowledge, principles and effects,
  In films and crystals, we're talking parts per million, respect.
  
  We got complete pn-control, that's the goal,
  Doping sensitization, got it under control.
  Using low-speed deposition, we go to the extreme,
  10 to the power of negative nine, that's the speed, supreme.
  
  And check it, emerging effects at the ppm level,
  Trap filling, majority carriers, it's a revel.
  Homojunction formation, mobility goes down,
  In organic single crystals, we run the town.
  
  Hall effect measurements, doping efficiency's high,
  We're talking 24 percent, reaching for the sky.
  Wannier excitonic doping, band conduction's the key,
  Defect science, trapping carriers, it's a new field, you see.
  
  Now, let's talk about the dawn of organic crystal electronics,
  It's a revolution, breaking all the skeptics.
  So remember this rap, 'cause it's straight-up facts,
  Doped organic semiconductors, that's where it's at.
