In this contribution, we describe the working prin- ciples of organic field effect transistors. To place it in con- text, we start with a brief description of some aspects of semiconductor field effect transistors. We then describe the standard struc

Semiconducting polymers and small molecules form an extremely flexible class of amorphous materials that can be used in a wide range of applications, some of which are display, radio-frequency tags, and solar cells. The rapid progress towards functio

We examine the role of the density of states in determining the performance of amorphous organic devices. Specifically we compare the exponential density of states and the Gaussian density of states. We find that the shape of the density of states af

We present self consistent picture of charge injection and transport in low mobility disordered organic based devices. We demonstrate the importance of accounting for charge density effects in both modeling and analysis of devices. We outline a metho

The electronic transport in organic semiconducting polymers have been studied extensively in the past decades . Among the physical pictures suggested the most widely accepted one is that of hopping-transport in a disordered-system having a Gaussian d

The device-physics features of organic materials are presented from an engineering point of view. By treating the organic material and the device in a self-consistent manner the unique features of organic devices are revealed. We discuss charge injec

We use digital holographic microscopy and Mie scattering theory to simultaneously characterize and track individual colloidal particles. Each holographic snapshot provides enough information to measure a colloidal sphere's radius and refractive index

The holographic optical trapping technique creates arbitrary three-dimensional configurations of optical traps, each with individually specified characteristics. Holographic modification of the individual traps' wavefronts can transform conventional

Optical traps use the forces exerted by structured beams of light to confine and manipulate microscopic objects in three dimensions. A popular implementation involves structuring the trap-forming beam with computer-generated holograms before focusing

We present the Kelvin probe force microscopy measurements of the Einstein relation, i.e., the relation between the diffusion coefficient of charge carriers and their mobility, in undoped and doped disordered organic thin films. The theoretical predic
