Thin Solid Films. 518:4019-4023
Zinc oxide based thin film transistors (TFT) fabricated by a non-aqueous sol–gel solution process with a zinc neodecanoate precursor are demonstrated. X-ray diffraction measurement reveals that the ZnO films adopt a hexagonal structure with a rando

The transient terahertz radiation emitted by a spin coherence optically generated in CdMnTe two-dimensional electron gases is directly measured in the time domain using electro-optic sampling. The spin radiation decays in a few ps at high magnetic fi

We show that it is possible to fix the carrier phase of a quantum cascade laser (QCL) by using injection seeding. Terahertz (THz) pulses with a fixed phase are injected into the QCL cavity and coincide with the gain of the QCL being turned on rapidly

Laser action normally is initiated by the amplification of spontaneous emission. As spontaneous emission is a random process, the carrier phase of a laser is different each time a laser is turned on. As a consequence, it is not possible to measure th
