摘要:
 针对混合成分二维半导体的研究需求,利用高温箱式炉进行各组分多晶的合成,并在高温三温区管式炉中,利用四氯化碲(TeCl4)作为输运剂,采用气相输运法(chemical vapor transport, CVT)生长出MoSxSe2-x混合成分二维半导体块材.将所生长出的块材利用机械剥离法进行剥离,并对剥离出的单层二维材料进行了光致发光(photoluminescence,PL)谱线检测,测得其混合成分对材料特征谱线的影响.结果表明:混合成分材料的光致发光谱线由其组成各组分的谱线叠加而成,并且叠加时近似按混合成分比例代数叠加.
Abstract:
 To meet the requirement of research on mixedcomponent 2D semiconductor material, chamber furnace was employed to synthesize polycrystalline. Then a variety of polycrystalline components were mixed and then put into a three-temperature-zone-furnace to grow MoSxSe2-x single crystal by chemical vapor transport (CVT), with tellurium(IV) chloride(TeCl4) as a transport agent. Monolayer MoSxSe2-x was exfoliated from the single crystal using mechanical exfoliation method. Photoluminescence (PL) was adopted to study the effect of the components on PL response of those samples. Results show that the PL spectrum of the mixed materials can be roughly considered as superposition of spectral response of each component by mixing ratio.
