  • development of CZTS based solar cell 
    Dilshan, HADI; Weerasinghe, WDD; Attygalle, D [Conference-Abstract]
    The two semiconductor layers Cu2ZnSnS4 (CZTS) and CdS were successfully fabricated using economical, solution-based fabrication techniques. CZTS thin film fabrication was done by spin coating technique onto soda-lime ...
  • Development of metal oxide based solid state gas sensor platform 
    Udaraka, MPSD; Nanayakkara, HATV; Attygalle, D; Amarasinghe, DAS [Conference-Abstract]
    Gas sensors are chemical sensors which have a transducer and an active layer for converting the chemical information into another form of electronic signal. Gas detection and determining the composition of a gas in a ...
  • Development of spark emission spectrometer to identify an alloy 
    Gunerathne, MGGM; Karunasena, DBTK; Attygalle, D; Amarasinghe, DAS [Conference-Abstract]
    Spark optical emission spectrometer (OES) is a widely used technique in identifying alloy compositions of metals. Based on the OES principle, a low-cost spark, portable and fully automated spark optical emission spectrometer ...
  • Investigation of laser scribing technique for graphite oxide reduction and patterning 
    Prasath, M; Jayasinghe, JGDSD; Attygalle, D [Conference-Abstract]
    Engineering a low cost graphene-based electronic device has proven difficult to accomplish via a single-step fabrication process. An infrared laser assisted technique to reduce graphite oxide (GO) to graphene, at ambient ...
  • Study of the dielectric behavior of graphite oxide upon exposure to chlorine 
    Silva, SM; Kulathilake, PHD; Attygalle, D; Amarasinghe, DAS [Conference-Abstract]
    Graphite Oxide (GO) was synthesized using the Improved Hummer’s Method. After the successful synthesis of GO, it was characterized and its dielectric properties were investigated. The change of dielectric behavior of GO ...
