An InGaAS/GaAs heterostructure transistor utilizing a graded In x Ga 1-x As channel grown by low-pressure metal-olorganic chemical vapor deposition has been demonstrated. A negative differential resistance (NDR) phenomenon is observed. Electron mobilities are significantly improved by using the grad
