Negative activation energy and dielectric signatures of excitons and excitonic Mott transitions in quantum confined laser structures
Amit Bhunia, Kanika Bansal, Mohamed Henini +2
Mostly, optical spectroscopies are used to investigate the physics of excitons, whereas their electrical evidences are hardly explored. Here, we examined a forward bias activated d…
Dynamic frequency dependence of bias activated negative capacitance in semiconductor diodes under high forward bias
Kanika Bansal, Mohamed Henini, Marzook S. Alshammari +1
We observed qualitatively dissimilar frequency dependence of negative capacitive response under high charge injection in two sets of junction diodes which are functionally differen…
Electrical Signature of Excitonic Electroluminescence and Mott Transition at Room Temperature
Kanika Bansal, Shouvik Datta
Mostly optical spectroscopies are used to investigate existence of excitons, Mott transitions and other exquisite excitonic condensed phases of matter. On the other hand, electrica…
Temperature dependent reversal of voltage modulated light emission and negative capacitance in AlGaInP based multi quantum well light emitting devices
Kanika Bansal, Shouvik Datta
We report a reversal in negative capacitance and voltage modulated light emission from AlGaInP based multi-quantum well electroluminescent diodes under temperature variation. Unlik…
