現(xiàn)在有一個(gè)機(jī)會,有一名博士生名額,主要是用VASP計(jì)算。 主要工作涉及: Phosphors for LEDs Activity Type: RTD Participant: IIC-SAS Objectives: preparation of light emitting phosphors available for LEDs based on ternary nitrides and oxonitride (SiAlON) by reaction synthesis, combustion synthesis and carbothermal reduction and nitridation process. Description of work: Following tasks will be performed: (i) reaction synthesis, combustion synthesis and carbothermal reduction and nitridation (CTRN) synthesis of ternary nitrides via nitridation of Si, Si3N4 and metal silicide powder mixture, (ii) first principle calculations of the electronic structure (including band gap) in ternary nitrides, (iii) synthesis of Eu2+ and Eu3+ doped ternary nitrides, (iv) optimization of composition and annealing conditions of nitride-based phosphors, (v) optical characterization, (vi) fabrication of thin layers of luminescent ternary nitrides; (vii) feasibility studies of possible application for LED technologies. The phase composition of synthesized powders will be determined by X-ray analysis, N/O analysis and IR spectroscopy. The morphology of grains will be studied by scanning electron microscopy. More precise analysis of the synthesised nitride/oxonitride grains will be analysed by means of EDX and EELS and carried out in co-operation with the project partners. The luminescent properties of lanthanoid-doped nitrides (and oxonitrides) will be determined in the Femtosecond Spectroscopy Laboratory of the International Laser Centre, Bratislava, Slovakia. The electronic structure (including band gap) of ternary nitrides will be calculated by first principle calculations using the Vienna ab initio simulation package (VASP) which performs an iterative solution of the Kohn-Sham equation of the density-functional theory (DFT, UR). Recruited researchers to be involved: two ESRs 要求是熟練掌握VASP。 條件是可以和國內(nèi)聯(lián)合培養(yǎng),也可以放棄國內(nèi)學(xué)位直接拿國外學(xué)位。由于該項(xiàng)目是合作性項(xiàng)目,因此經(jīng)常會在歐洲國家走動(dòng)。 如果有意向的可以先發(fā)郵件,如果可行,然后直接和老板商量。 由于有時(shí)間限制,請有意向的抓緊時(shí)間聯(lián)系。 Email:wangyonl@gmail.com |

這里是連接 http://www.funea.tu-darmstadt.de/funea/research/wp9/wp9_1.en.jsp 我也是幫一個(gè)熟悉的老師聯(lián)系的,可以先看看這個(gè)鏈接。 祝好 |
