The results show a marked difference in the lifetime on n-type InP and p-type InP of similar doping levels. N-type InP shows a lifetime considerably longer than the expected radiative limited lifetime.<<ETX>>","PeriodicalId":6444,"journal":{"name":"[Proceedings 1991] Third International Conference Indium Phosphide and Related Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1991-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80800522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The implanted diodes do not show the H4 (0.38 eV) level, casting doubt on the Frenkel pair, V/sub p/-P/sub i/, identity assignment. Carrier loss and degradation of V/sub oc/, I/sub sc/, and cell efficiency correlate with the production of dominant hole traps H4 and H3.

The monolayer splitting of very thin quantum wells was used to characterize the interface structures in the lateral plane. Scanning cathodoluminescence (SCL) images provide information on the size and lateral distribution of the growth islands.

FTPL identified recombination processes at low and room temperature and carrier types of InGaAs films through correlation of 4.2 K and 293 K PL emissions. XRD measurements determine the extent of film relaxation and the composition. The strained nature of the InGaAs films is suggested by the correlation of low temperature PL bandgap energy and XRD composition.

In the buried grating DFB (BG-DFB) laser, the coupling coefficient (Kl) of the laser optical mode to the feedback grating can be reproducibly and accurately adjusted by changing the thickness of the grating layer or the distance of the grating from the active region. The coupling coefficient can be adjusted over a large range without altering the waveguide parameters of the laser. The duty cycle (ratio of InGaAsP grating segment width to grating period) of the grating can be changed by adjusting the grating etch parameters. This provides another means to optimize the reflectivity and output coupling of second order gratings for grating surface emitter lasers.<<ETX>>","PeriodicalId":6444,"journal":{"name":"[Proceedings 1991] Third International Conference Indium Phosphide and Related Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1991-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76981245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
