In this work, the liquid phase epitaxy (LPE) technique was used to grow Al(x)Ga(1-x)Sb layers with different composition of x value from 0.03 to 0.15 on GaSb substrate, this cause a substitution of gallium by aluminium atoms. The High Resolution X-ray diffraction (HRXRD) was used to determine the lattice parameters of AlGaSb layers, the mismatch to substrate and the relaxation of layer. The composition was studied by x-ray fluorescence (XRF). In this study the substitution of atoms creates tensile stress and relaxation, its lattice parameters follows the Vegard's law in function of composition, also, the composition changes the operation wavelength for the potential use in optoelectronic device.","keywords":"X-Ray; Fluorescence; Diffraction; semiconductor alloy","status":"active","sarx_st":"accepted","user_id":237,"created_at":"2016-07-12 00:17:49","updated_at":"2016-08-20 12:40:48","filename":"Abstract (SARX2016) Primavera.doc","mode":"oral","sarx_code":"15_O-XRD","poster_group":null,"file":"022babd96cb22952d95a99b7e3767166.doc","author":"Primavera L\u00f3pez Salazar","affiliation":"Dr \/<\/b> Benemerita Universidad Autonoma de Puebla \/<\/b> Mexico","user":{"id":237,"name":"Primavera L\u00f3pez Salazar","degree":"Dr","email":"prim_07@hotmail.com","username":"prim_07@hotmail.com","confirmed":1,"confirmation_code":null,"created_at":"2016-07-12 00:06:10","updated_at":"2016-09-19 09:03:29","sarx":1,"affiliation":"Benemerita Universidad Autonoma de Puebla","address":"Av 14 Sur y Av San Claudio Ciudad Universitaria","zipcode":"72570","state":"Puebla","phone":"+522223211547","fax":null,"city":"Puebla","country":"Mexico","status":"active","is_admin":0,"category":"student","school":0,"icdd":0}}}
