InGaAsN is a promising material system to enable low-cost GaAs-based detectors to operate in the telecommunication spectrum, despite the problems posed by the low growth temperature required for nitrogen incorporation. We demonstrate that InGaAsN p-i-n structures with nominal In and N fraction of 10% and 3.8%, grown by molecular beam epitaxy (MBE) under non-optimal growth conditions, can be opt...
In this paper, we reported the effective mobility and the interface-state density of La2O3 nMISFETs fabricated under different post deposition annealing (PDA) conditions; annealing temperature (300 ◦C – 600 ◦C) and ambient (N2 or O2). High effective mobility of 312 cm2/Vs and low interface-state density of 6 × 1010 cm−2/eV were obtained from La2O3 nMISFET with equivalent oxide thickness (EOT) o...
Ultrafine grained sheets were prepared from a twin-roll cast AA8006 aluminium alloy using accumulative roll-bonding process at room temperature. The evolution of microstructure of sheets after three accumulative roll-bonding passes during isochronal annealing with a constant step of 20 °C/20 min was studied by light and electron microscopy. The influence of the resulting microstructure on mecha...
The effects of post-deposition annealing on optical and electrical properties of thermallyevaporated ITO/Ag/ITO films have been investigated. The thickness of ITO, Ag and ITO films in the multilayered structure was constant at 50, 10 and 40 nm. The multilayered films were deposited on glass substrate without intentional substrate heating. A significant variation in resistivity and transparency ...
We studied the optical properties of metalorganic chemical vapour deposited (MOCVD) InGaN/GaN multiple quantum wells (MQW) subjected to nitrogen (N) implantation and post-growth annealing treatments. The optical characterization was carried out by means of temperature and excitation density-dependent steady state photoluminescence (PL) spectroscopy, supplemented by room temperature PL excitatio...
A selective electrothermal magnetic annealing technique is introduced that provides programming capabilities for mechanical micro-resonators. In the proposed approach the magnetic properties of resonators can be locally tuned in a post-fabrication batch-compatible process step. A prototype is implemented in a standard microfabrication process, where resonating ferromagnetic elements are suspend...
