Abstract

We have studied the dependence of current-voltage characteristics of Organic Light Emitting Diodes(OLEDs) on temperature-dependent variation. The OLEDs have been based on the molecular compounds. N,N'-diphenyl-N,N'-bis(3-methylphenyl)-1, 1'- biphenyl-4, 4'-diamine (TPD) as a hole transport. tris(8-hydroxyquinolinoline) aluminum (III) ($Alq_3$) as an electron transport and Poly(3,4-ethylenedioxythiophene) (PEDOT:PSS) as a buffer layer. The current-voltage characteristics were measured in the temperature range of 10K and 300K. A conduction mechanism in OLEDs has been interpreted in terms of space-charge-limited current(SCLC) and tunneling region.Ā᐀會Ā᐀衅?⨀頱岒ᄀĀ저會Ā저?⨀⡌ឫഀĀ᐀會Ā᐀㡆?⨀쁌ឫഀĀ᐀會Ā᐀遆?⨀郞ග瀀ꀏ會Ā?⨀〲岒ऀĀ᐀會Ā᐀䁇?⨀젲岒Ā㰀會Ā㰀顇?⨀끩Ā㈀會Ā㈀?⨀䡪ഀĀ᐀會Ā᐀䡈?⨀Ā᐀會Ā᐀ꁈ?⨀硫Ā저會Ā저?⨀샟ගऀĀ저會Ā저偉?⨀栰岒ഀĀ저會Ā저ꡉ?⨀1岒ഀĀ저會Ā저J?⨀惝ග؀Ā؀會Ā؀塊?⨀ග䈀Ā切
