Nontrivial capacitance behavior, including a negative capacitance (NC) effect, observed in a variety of semiconductor devices, is discussed emphasizing the physical mechanism and the theoretical interpretation of experimental data. The correct interpretation of NC can be based on the analysis of the time-domain transient current in response to a small voltage step or impulse, involving a self-consistent treatment of all relevant physical effects (carrier transport, injection, recharging etc… 
Ferroelectric negative capacitance
The capacitor is a key element of electronic devices and is characterized by positive capacitance. However, a negative capacitance (NC) behaviour may occur in certain cases and implies a local
Impacts of Minority Charge Carrier Injection on the Negative Capacitance, Steady‐State Current, and Transient Current of a Single‐Layer Organic Semiconductor Device
Space charge limited current theory is often used to analyze electrical characteristics of single‐layer organic semiconductor devices using Ohmic and Schottky contacts for injection of majority and
Origin of apparent light-enhanced and negative capacitance in perovskite solar cells
It is shown that apparently high capacitances in general (positive and negative) are not related to any capacitive feature in the sense of a corresponding charge accumulation, and are a natural consequence of slow transients mainly in forward current of the diode upon ion displacement when changing voltage.
Ferroelectric Negative Capacitance Field Effect Transistor
With the progress in silicon circuit miniaturization, lowering power consumption becomes the major objective. Supply voltage scaling in ultralarge‐scale integration (ULSI) is limited by the physical
Negative contribution to the reverse bias capacitance of organic diodes due to field dependent mobility: Determination of barrier height and transport parameters
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
The two faces of capacitance: New interpretations for electrical impedance measurements of perovskite solar cells and their relation to hysteresis
Perovskite solar cells are notorious for exhibiting transient behaviour not seen in conventional inorganic semiconductor devices. Significant inroads have been made into understanding this fact in
Negative impedance of organic light emitting diodes in AC electrical response
In previous papers, we introduced a novel analysis technique of the impedance spectroscopy of organic light emitting diodes to elucidate their layer-to-layer carrier dynamics and proposed a novel
Consistent Device Simulation Model Describing Perovskite Solar Cells in Steady-State, Transient and Frequency Domain.
The analysis of the transient current upon voltage turn-on in the dark reveals that the charge injection properties of the interfaces are triggered by the accumulation of mobile ionic defects, leading to a deeper understanding of the physical effects in these materials.
