Determination of the strains in and around the quantum dots is important both to assess the results of the epitaxially grown thin film and to explain the optical performance of quantum dots samples. A series of InAs/GaAs quantum dots samples were fabricated by MBE in Stranski-Krastanov growth mode. The preliminary results of ion-channeling observations along < 001 > growth direction and < 011 > direction will be presented and discussed briefly. (c) 2005 Elsevier B.V. All rights reserved.

VOLTAGE-CONTROLLED oscillators (VCOs) providing wide tuning ranges are useful components in applications such as wireless communications systems. When designing VCOs, it is important to account for the effects of parasitics generated by the active device and circuit layout. A procedure for predicting the tuning bandwidth of wideband VCOs was applied to the design of a Colpitts oscillator operating at UHF.
