“…Moreover, the addition of CO or H 2 into the gas mixture CO : Ar enabled us to enhance the maximum electric field strength (E/p) max in the EBSD and, accordingly, to significantly increase the value of the SIE Q m (figures 5 and 6). It should be pointed out that the same effect was observed in [22][23][24], where an addition of CO to nitrous oxide N 2 O resulted in considerable enhancement of the SIE in the EBSD and the development of an efficient N 2 O laser. In both cases, the major function of carbon monoxide is the decrease of the negative ions O − in a discharge due to the reaction…”

The possibility of obtaining a high specific input energy in an electron-beam sustained discharge ignited in oxygen gas mixtures O 2 : Ar : CO (or H 2) at the total gas pressures of 10-100 Torr was experimentally demonstrated. The specific input energy per molecular component exceeded ∼6 kJ l −1 atm −1 (150 kJ mol −1) as a small amount of carbon monoxide was added into a gas mixture of oxygen and argon. It was theoretically demonstrated that one might expect to obtain a singlet delta oxygen yield of 25% exceeding its threshold value needed for an oxygen-iodine laser operation at room temperature, when maintaining a non-self-sustained discharge in oxygen gas mixtures with molecular additives CO, H 2 or D 2. The efficiency of singlet delta oxygen production can be as high as 40%.

The pressure dependences of the electrical conductivity and Hall coefficient have been studied for GaAs and AI,Ga, _,As ( x = 0.20 and 0.25) heavily doped with Te. The results obtained show that for a GaAs crystal the resonant donor level related to Te is located approximately 0.45 eV above the conduction band minimum. The effect of persistent photoconductivity observed at high pressures proves t h e DX-like character of this donor state. Comparison of the data on the energetic position of the DX level illustrates its strong chemical energetic dependence (for Si, Sn and S dopants an E,, value of around 0.3 eV has been reported previously). It appears that Te represents an impurity which is very suitable for testing the microscopic models of the DX centre. Studies of processes of the thermal recovery after high pressure freeze-out of electrons on the metastable states of the DX centres clearly demonstrate the multicomponent structure of t h e DX state in AlGaAs samples.
