Term\u00e9szetesen amerikai kutat\u00f3knak m\u00e1r erre is van egy m\u00e9g gyerekcip\u0151ben j\u00e1r\u00f3, de haszn\u00e1lhat\u00f3nak t\u0171n\u0151 megold\u00e1sa.<\/p>\n

De hogyan \u00e9rt\u00e9k ezt el?<\/h3>\n

A Michigani Egyetem csapata m\u00f3dos\u00edtott egy infrav\u00f6r\u00f6s rizsszem m\u00e9ret\u0171 fotodi\u00f3d\u00e1t. Sim\u00edtott felsz\u00edn\u00e9vel egy h\u0151mennyis\u00e9gm\u00e9r\u0151 mell\u00e9 helyezt\u00e9k, mind\u00f6sszesen 55 nanom\u00e9ter t\u00e1vols\u00e1gba. A h\u0151mennyis\u00e9gm\u00e9r\u0151 adatai alapj\u00e1n a fotodi\u00f3da negat\u00edv ir\u00e1nyban m\u0171k\u00f6dtetve h\u0151m\u00e9rs\u00e9klet cs\u00f6kken\u00e9st eredm\u00e9nyezett.<\/p>\n

Ez a megk\u00f6zel\u00edt\u00e9s az elektronikus eszk\u00f6z\u00f6k h\u0171t\u00e9s\u00e9nek egy \u00faj korszak\u00e1hoz vezethet, ami sz\u00fcks\u00e9ges is lesz a nagy iram\u00fa fejl\u0151d\u00e9s nyom\u00e1n, a tranzisztorok egyre kisebb helyen l\u00e9v\u0151 egyre nagyobb mennyis\u00e9ge miatt.<\/p>\n

A kutat\u00f3k \u2013 prof. Pramod Reddy \u00e9s prof. Edgar Mayhofer \u2013 a h\u0151sug\u00e1rz\u00e1s k\u00e9miai potenci\u00e1lj\u00e1t kihaszn\u00e1lva \u00e9rt\u00e9k el az eredm\u00e9nyt.<\/p>\n

\u2013 M\u00e9g ma is sokan azt hiszik, hogy a sug\u00e1rz\u00e1s k\u00e9miai potenci\u00e1lja semmis \u2013 \u00e1ll\u00edtja Mayhofer. \u2013 De a ’80-as \u00e9vekig visszavezethet\u0151 elm\u00e9leti kutat\u00e1s azt igazolja, hogy ez nem igaz.<\/p>\n

Linxiao Zhu szerint: \u2013 \u00c1ltal\u00e1ban a h\u0151sug\u00e1rz\u00e1s eset\u00e9ben az intenzit\u00e1s kiz\u00e1r\u00f3lag a h\u0151m\u00e9rs\u00e9kleten m\u00falik, de van m\u00e9g egy t\u00e9nyez\u0151, amivel befoly\u00e1solni lehet a sug\u00e1rz\u00e1st, \u00e9s ami miatt a h\u0171t\u0151 hat\u00e1s, amit vizsg\u00e1lunk, lehets\u00e9gess\u00e9 v\u00e1lik.<\/p>\n

Ez a t\u00e9nyez\u0151 pedig maga az elektromoss\u00e1g. Elm\u00e9letileg ha megford\u00edtjuk a pozit\u00edv \u00e9s negat\u00edv csatlakoz\u00e1sokat az infrav\u00f6r\u00f6s LED-en, akkor nem csak a f\u00e9nykibocs\u00e1t\u00e1s sz\u0171nik meg, de elnyeli a k\u00f6rnyez\u0151 h\u0151sug\u00e1rz\u00e1st.<\/p>\n

\"\"\u2013 A megford\u00edtott LED \u00fagy viselkedik, mintha szobah\u0151m\u00e9rs\u00e9klet alatt lenne \u2013 magyar\u00e1zza a jelens\u00e9get Reddy, az egyik vezet\u0151 kutat\u00f3.<\/p>\n

De ezt a h\u0171t\u00e9st m\u00e9rni \u00e9s bizony\u00edtani, hogy b\u00e1rmi jelent\u0151s t\u00f6rt\u00e9nt, meglehet\u0151sen komplik\u00e1lt.<\/p>\n

Ahhoz, hogy eredm\u00e9nyes lehessen a k\u00eds\u00e9rlet, a k\u00e9t fel\u00fcletnek hihetetlen k\u00f6zel kell lennie egym\u00e1shoz \u2013 eg\u00e9sz pontosan k\u00f6zelebbnek, mint amilyen hossz\u00fa egy infrav\u00f6r\u00f6s f\u00e9nyhull\u00e1m.<\/p>\n

A v\u00e9geredm\u00e9ny sz\u00e1m szerint 6 watt h\u0171t\u00e9s egy n\u00e9gyzetm\u00e9teren, de elm\u00e9letileg 1000 watt\/m^2 h\u0171t\u00e9st is el lehet \u00e9rni vele, ami a Nap a F\u00f6ldre bocs\u00e1tott h\u0151energi\u00e1j\u00e1nak felel meg. Ezen felismer\u00e9s hasznos lehet a j\u00f6v\u0151 okostelefonjai \u00e9s egy\u00e9b informatikai eszk\u00f6zei kapcs\u00e1n.<\/p>\n","protected":false},"excerpt":{"rendered":"
