Innovations in Insurance, Risk- and Asset Management.
Behavioral risk affects the pricing of assets and liabilities with embedded pre-payment/extension options whenever the option holder does not act purely on the strength of financial convenience but follows an uncertain and sub-optimal exercise strate

We use a combination of magneto-tunnelling and photoluminescence spectroscopy techniques to explore the admixing of the extended GaAs conduction band states with the localised N-impurity states in dilute GaAs 1 - y N y quantum wells (QWs) incorporate

Hydrogen irradiation leads to the passivation of the electronic activity of nitrogen in Ga(AsN), thus allowing a fine tuning of the material optical properties. Here, some recent results on the effects that hydrogen irradiation has on the electronic

Microphotoluminescence and resonant photoluminescence experiments in a variety of InGaAs quantum dots (QD's) differing for size, shape, indium content, and growth technique are reported. In the case of large QD's, the excited state energies determine

We report on the effects of N incorporation on the electronic properties of (InGa)(AsN)/GaAs heterostructures as investigated by photoluminescence (PL) spectroscopy. PL under a magnetic field shows an increase in the electron effective mass in the N-

The effects of H irradiation on the optical properties of GaAs 1-y N y epilayers in the dilute N limit have been studied. H irradiation leads to a progressive and finally complete passivation of bound exciton levels related to N complexes. A further

Photoluminescence and photoreflectance spectroscopy are used to investigate the electronic properties of InxGa1−xAs1−yNy/GaAs heterostructures treated with low-energy atomic hydrogen. With increasing hydrogen doses, the InxGa1−xAs1−yNy optica
