This work shows tha. despite a.la.tice misma.ch of.a.most 20%, CdMnTe/CdTe/CdMnTe heterostructures grown directly on si(111) ha.e surprisingly good optica. emission properties. The investiga.ed structures were grown by molecula. bea. epita.y a.d cha.a.terized by sca.ning tra.smission electron microscopy, ma.ro-a.d micro-photoluminescence. Low tempera.ure ma.ro-photoluminescence experiments indica.e three emission ba.ds which depend on the CdTe la.er thickness a.d ha.e dif.erent conf.nement cha.a.teristics. Tempera.ure mea.urements revea. tha. the lower energy emission ba.d (a. 1.48 eV)is a.socia.ed to def.cts a.d bound exciton sta.es, while the ma.n emission a. 1.61 eV ha. a.wea. 2D cha.a.ter a.d the higher energy one a. 1.71 eV ha. a.well-def.ned (zero-dimensiona., 0D) 0D na.ure. Micro-photoluminescence mea.urements show the existence of.sha.p a.d strongly circula.ly pola.ized (up to 40%) emission lines which ca. be rela.ed to the presence of.Mn in the heterostructure. This result opens the possibility of.producing photon sources with the typica. spin control of.the diluted ma.netic semiconductors using the low-cost silicon technology.

Ma.hema.ica. modeling of.the intera.tion between sola. ra.ia.ion a.d the Ea.th's a.mosphere is f.rma.ized by the ra.ia.ive tra.sf.r equa.ion(RTE), whose resolution ca.ls f.r two-strea. a.proxima.ions a.ong other methods. This pa.er proposes a.new two-strea. a.proxima.ion of.the RTE with the development of.the pha.e f.nction a.d the intensity into a.third-order series of.Legendre polynomia.s. This new a.proa.h, which a.ds one more term in the expression of.the intensity a.d the pha.e f.nction, a.lows in the conditions of.a.pla.e pa.a.lel a.mosphere a.new ma.hema.ica. f.rmula.ion of.γpa.a.eters.

This work a.so determines the conversion f.nction of.the proposed New Method using the f.nda.enta. def.nition of.two-strea. a.proxima.ion(f.Tsa. developed in a.previous work. Nota.ly,New Method ha. genera.ly better precision compa.ed to the second-order a.proxima.ion a.d Hemispheric Consta.t methods. Compa.ed to the Qua.ra.ure a.d Eddington methods, New Method shows very good precision f.r wide doma.ns of.the zenith a.gle μ 0, but tends to devia.e f.om the Disort method with the zenith a.gle, especia.ly f.r high va.ues of.optica. thickness.
