Negative contribution to the reverse bias capacitance of organic diodes due to field dependent mobility: Determination of barrier height and transport parameters
Abstract
We analyse the capacitance voltage characteristics of a small molecule-based single carrier diode consisting of a p-doped/intrinsic layer interface using m-MTDATA. In such homojunction diodes, in which the intrinsic layer thickness vari...

TIPS-pentacene based MIS structure using a polymer insulator: role of interface traps studied using HMDS treatment, frequency and light intensity
Abstract
Though it is well known that the characteristics of solution-processed polymer based organic thin film transistors depend crucially on the semiconductor/polymer interface. The mechanisms of charge processes are not understood well. We s...

Impact of defect states on the capacitance voltage characteristics of space charge limited organic diodes, and determination of defect states
Abstract
We investigate the frequency dependent capacitance–voltage (C–V) characteristics of space charge limited organic diodes based on m-MTDATA, which is a well characterized model material system. The low frequency C–V curves show an intense...

MoS2|ZnO isotype heterostructure diode: Carrier transport and band alignment
Abstract
Molybdenum disulfide (MoS2) is one of the most studied semiconducting materials among the class of layered transition metal dichalcogenides (TMDCs). Though there has been an intense focus on its monolayers, multilayer MoS2 (m-MoS2) also...

Determination of interlayer electron mobility in multilayer MoS2 flake using impedance spectroscopy
Abstract
Layered molybdenum disulfide (MoS2) is emerging as a promising candidate for novel electronic applications, though the focus has largely been on few-layered thin films and in-layer electrical properties. MoS2 shows various nontrivial de...

Dielectric constant of thin film graphitic carbon nitride (g-C3N4) and double dielectric Al2O3/g-C3N4
Abstract
Graphitic carbon nitride (g-C3N4), a highly stable wide bandgap material, is yet to be evaluated for thin-film applications in devices since its basic electrical properties are not understood. We study its vacuum-deposited thin film for...
