Ma LED owala kwambiri ndi ma laser akhala gawo la moyo wathu ndipo amagwiritsidwa ntchito powunikira wamba komanso mumitundu yosiyanasiyana yamagetsi yoyezera. Ukadaulo wopanga pogwiritsa ntchito mawonekedwe amafilimu opyapyala amatha kutengera zida za semiconductor kukhala zatsopano. Mwachitsanzo, ma transistors a filimu opyapyala apangitsa ukadaulo wamadzimadzi amadzimadzi kuti ukhale ponseponse komanso wofikirika m'njira zomwe sizikanatheka ndi ma transistors okha.
Ku Ulaya, ntchito yopanga ukadaulo wopanga ma LED opanga mafilimu ndi ma semiconductor lasers idaperekedwa kwa wasayansi wotchuka waku Belgian microelectronics Paul Heremans. Pan-European Council European Research Council (ERC), yomwe imagawira ndalama zothandizira zomwe zikuchitika ku Europe, idapatsa Paul Hermans thandizo kwa zaka zisanu zomwe zimakwana 2,5 miliyoni mayuro. Aka si koyamba thandizo la ERC Hermans kulandira. Panthawi ya ntchito yake ku Belgian Research Center Imec, adatsogolera ntchito zambiri zopambana pa chitukuko cha semiconductor, makamaka, mu 2012, Hermans adalandira thandizo la ntchito yopanga ma crystalline organic semiconductors.
Ma LED opanga mafilimu ndi ma laser akuyembekezekanso kupangidwa pogwiritsa ntchito zinthu zachilengedwe. Masiku ano, ma LED amafilimu ochepa kwambiri amakhala ndi kuwala komwe kumakhala kofooka nthawi 300 kuposa ma LED owala kwambiri otengera zida zamagulu a III-V a tebulo la periodic. Cholinga cha Hermans chidzakhala kubweretsa kuwala kwa mafilimu opyapyala kufupi ndi kuthekera kwa anzawo ang'onoang'ono. Panthawi imodzimodziyo, zidzakhala zotheka kupanga mapangidwe a filimu yopyapyala pazigawo zoonda komanso zosinthika kuchokera kuzinthu zosiyanasiyana, kuphatikizapo pulasitiki, galasi ndi zitsulo.
Kupita patsogolo kutsogoloku kudzapangitsa kuti zitheke kupititsa patsogolo madera ambiri odalirika. Izi zikuphatikiza ma silicon photonics, zowonetsera zomverera zowoneka bwino, ma lidar amagalimoto odziyendetsa okha, ma spectrometer a makina owunikira pawokha, ndi zina zambiri. Chabwino, tiyeni timufunire zabwino zonse mu kafukufuku wake ndi kuyembekezera nkhani zosangalatsa.
