Answer: Indium(III) phosphide is a semiconducting material
Chapter 18, Problem 18.123(choose chapter or problem)
Indium(III) phosphide is a semiconducting material that has been frequently used in lasers, light-emitting diodes (LED), and fiberoptic devices. This material can be synthesized at 900. K according to the following reaction: In(CH3)3(g) 1 PH3(g) 88n InP(s) 1 3CH4(g) a. If 2.56 L In(CH3)3 at 2.00 atm is allowed to react with 1.38 L PH3 at 3.00 atm, what mass of InP(s) will be produced assuming the reaction is 87% efficient? b. When an electric current is passed through an optoelectronic device containing InP, the light emitted has an energy of 2.03 3 10219 J. What is the wavelength of this light, and is it visible to the human eye? c. The semiconducting properties of InP can be altered by doping. If a small number of phosphorus atoms are replaced by atoms with an electron configuration of [Kr]5s24d105p4, is this n-type or p-type doping?
