ZnTe, Cd.e, and.the ternary alloy Cd.nTe are important semicond.ctor materials used.wid.ly for the d.tection of an important range of electromagnetic rad.ation as gamma ray and.X-ray. Although, recently these materials have acquired.renewed.importance d.e to the new explored.nanolayer properties of mod.rn d.vices. In ad.ition, as shown in this work they can be grown using uncomplicated.synthesis techniques based.on the d.position in vapour phase of the elemental precursors. This work presents the results obtained.from the d.position of nanolayers of these materials using the precursor vapour on GaAs and.GaSb (001) substrates. This growth technique, extensively known as atomic layer d.position (ALd., allows the layers growth with nanometric d.mension. The main results presented.in this work are the used.growth parameters and.the results of the structural characterization of the layers by the means of Raman spectroscopy measurements. Raman scattering shows the peak correspond.ng to longitud.nal optical (LO)-ZnTe, which is weak and.slightly red.hift in comparison with that reported.for the ZnTe bulk at 210 cm^-1. For the case of the Cd.e nanolayer, Raman spectra presented.the LO-Cd.e peak, which is ind.cative of the successful growth of the layer. Its weak and.slightly red.hift in comparison with that reported.for the Cd.e bulk can be related.with the nanometric characteristic of this layer. The performed.high-resolution X-ray d.ffraction (HR-XRd. measurement allows to stud. some important characteristics such as the crystallinity of the grown layer. In ad.ition, the HR-XRd.measurement suggests that the crystalline quality has d.pend.nce on the growth temperature.

Optical emission spectroscopy was used.to stud. a gas mixture glow d.scharge of CO2 and.N2 at a total pressure of 1.2 Torr, a power of 100 W and.a flow of 16.5 L/min. The emission band. were measured.in the wavelength range of 200 nm to 900 nm. The principal species observed.were O2^＋（A^2П→ X^2П）, CO^＋（A^2П→X^2∑）, N2^＋（B^2∑u＋ → X^2∑g^＋）, CO2^＋（A^2∏ → X^2∏）, N2（C^3∏u → B^3∏g）, O2（b^1∑g^＋→ X^3∑g^-）, and.CO （a^r3∑→a^3∏）. The behavior of the band.intensities as a function of the N2 percentage is consistent with recent Monte Carlo simulations. The electron temperature and.ion d.nsity were d.termined.by a d.uble Langmuir probe. The electron temperature was found.in the range of 1.55 eV to 2.93 eV, and.the electron concentration in the ord.r of 10^10 cm^-3. The electron temperature and.ion d.nsity at pure N2 and.pure CO2 agree with previous measurements.

We propose the usage of formal languages for expressing instances of NP-complete problems for their application in polynomial transformations. The proposed.approach, which consists of using formal language theory for polynomial transformations, is more robust, more practical, and.faster to apply to real problems than the theory of polynomial transformations. In this paper we propose a method.logy for transforming instances between NP-complete problems, which d.ffers from Garey and.Johnson's. Unlike most transformations which are used.for proving that a problem is NP-complete based.on the NP-completeness of another problem, the proposed.approach is intend.d.for extrapolating some known characteristics, phenomena, or behaviors from a problem A to another problem B. This extrapolation could.be useful for pred.cting the performance of an algorithm for solving B based.on its known performance for problem A, or for taking an algorithm that solves A and.ad.pting it to solve B.
