Influence of methane in the electrical properties of polypyrrole films doped with dodecylbenzene sulfonic acid

Sensitive detection of ammonia by reduced graphene oxide/polypyrrole nanocomposites

“…FTIR spectra of PPy exhibiting a peak at 1316.46 cm À1 which is due to the C-N stretching vibration in PPy [26]. In plane C-H mode (1048.44 cm À1 ) and out of plane C-H mode (966.50 cm À1 and 926.45 cm À1 ) are due to the PPy polymer chains [27][28][29]. In FTIR spectra of PPy/rGO composites (PG2.5 and PG5.0) the characteristic peaks of PPy at (3367 cm À1 , 1555.39 cm À1 and 1300.42 cm À1 ) are present which confirms the formation of the composite.…”

Determination of the laterally homogeneous barrier height of thermally annealed and unannealed Au/p-InP/Zn-Au Schottky barrier diodes

“…The ideality factors greater than unity are attributed to secondary mechanisms at the interface [4][5][6][7][8][9]33,34]. For example, interface defects may lead to a lateral inhomogeneous distribution of barrier heights at the interface which then results in larger ideality factors, and the charge transport across the interface only is no longer due to thermionic emission [1][2][3][4][5][6][7][8][33][34][35][36][37].…”

“…For example, interface defects may lead to a lateral inhomogeneous distribution of barrier heights at the interface which then results in larger ideality factors, and the charge transport across the interface only is no longer due to thermionic emission [1][2][3][4][5][6][7][8][33][34][35][36][37]. Ideality factors between 1.01 and 1.02 can be expected due to image force lowering of the Schottky barrier at the interface.…”

“…However, the fundamental mechanisms that determine the barrier height are still not fully understood [1][2][3][4][5][6][7][8][9]. It is only in the past decade that an inhomogeneous contact has been considered as an explanation for a voltage-dependent barrier height [10][11][12][13][14][15][16][17].…”

Direct current electrical conduction mechanism in plasma polymerized thin films of tetraethylorthosilicate

“…[1][2][3][4] have motivated the researchers to investigate the electrical properties of different organic materials. In such materials, the charge generation and transfer are important parameters to understand the electrical conduction process in organic thin film-metal structures.…”
