Etude théorique du transport électronique par la simulation Monte Carlo dans le quaternaire In0.863Ga0.137As0.3P0.7

Abstract: Afin de simuler le comportement d'un laser à semi-conducteur, nous devons disposer de modèles mathématiques décrivant de façons aussi précise que possible les propriétés physiques des matériaux considérés. Ces dernières années plusieurs recherches ont été consacrées aux lasers de type InGaAsP-InP. Plusieurs paramètres physiques sont connus avec une précision plus ou moins satisfaisante. Nous avons tenté, de reproduire au mieux l'ensemble des mesures rapportées dans la littérature et d'étudier le phénomène de t… Show more

“…Many studies on wurtzite GaN drift velocity characteristics have been performed, particularly theoretical predictions using analytical band and full band MC models. The simulated results [6,9,13,[16][17][18][19][20][21][22][23][24][25][26][27][28] show great discrepancy from each other and from the data derived from experimental measurements as depicted in figure 2. Although the drift velocity measurements of [20] show a similar trend to the theoretical work, the experimental results of [9,29] show that the peak drift velocity and the drop of drift velocity in negative differential resistance (NDR) region are much smaller than that predicted from theoretical simulations.…”
