The Ebers-Moll model for magnetic bipolar transistors [PDF]
, 2004 The equivalent electrical circuit of the Ebers-Moll type is introduced for magnetic bipolar transistors. In addition to conventional diodes and current sources, the new circuit comprises two novel elements due to spin-charge coupling.

Quantized Transport in Graphene p-n Junctions in Magnetic Field
, 2007 Recent experimental work on locally gated graphene layers resulting in p-n junctions have revealed quantum Hall effect in their transport behavior. We explain the observed conductance quantization which is fractional in the bipolar regime and integer in ...

Analysis of self-heating and negative capacitance in organic semiconductors devices [PDF]
, 2015 A numerical model for charge transport in organic semiconductor devices that accounts for self-heating is presented. In admittance spectroscopy this model reproduces the negative capacitance in bipolar, and more importantly, in single carrier devices. We
