Penghitungan konduktivitas optis graphene dengan algoritma gw berbasis tight binding = Optical conductivity calculation of graphene using tight binding based gw algorithm / Muhammad Avicenna Naradipa
" ABSTRAK
Skripsi ini didasari oleh tujuan kami untuk memahami terlahirnya eksiton di dalam graphene. Eksiton adalah quasipartikel yang mendeskripsikan keadaan terikat antara sebuah elektron dan sebuah hole. Eksiton memiliki peranan yang penting dalam teknologi berbasis semikonduktor, seperti photovoltaics, laser, dan sebagainya. Skripsi ini tidak semata-mata bertujuan untuk mendiskusikan tentang kemunculan eksiton, namun mengeksplorasi efek dari interaksi tolakmenolak Coulomb di antara elektron-elektron yang menghasilkan efek korelasi; Interaksi-interaksi ini memodi kasi spektrum satu partikel (kerapatan keadaan atau Density of States) dan spektrum dua partikel (konduktivitas optis) dari graphene. ...

A toy model to investigate the existence of excitons in the ground state of strongly correlated semiconductor = Model sederhana untuk menyelidiki pemunculan eksiton pada keadaan dasar semikonduktor terkorelasi kuat
" ABSTRACT
This study is motivated by a recent experimental study of the substrate material SrTiO3 STO showed the presence of excitonic signals originating from the optical conductivity has unique characteristics. Some exciton signals were found to have energy above the bandgap edge where as we have known that exciton formed from the excited electron bound to its hole that it has energy below the bandgap edge. We expect that excitons have been formed in the ground ... "

Optical conductivity calculation of a k.p model for ZnO incorporating electron hole interactions within first-order vertex correction = Perhitungan konduktivitas optis ZnO model k.p dengan memperhitungkan interaksi elektron-hole menggunakan koreksi vertex orde pertama
" ABSTRACT
The emergence of exitonic signal in the optical response of a wide band gap semiconductor has been a common knowledge in physics. There have been numerous experimental studies exploring the important role of excitons on influencing both the transport and optical properties of the materials. Typically, excitonic effect appears in the optical spectra of a wide band gap semiconductor as a rising signal below the onset energy of the band to band transition. Despite the ... "

Exciton polaritons in microcavities : new frontiers
" This monograph summarizes the current state of the art of research on exciton polaritons in microcavities: their interactions, fast dynamics, spin-dependent phenomena, temporal and spatial coherence, condensation under non-equilibrium conditions, related collective quantum phenomena and most advanced applications. The monograph is written by the most active authors who have strongly contributed to the advances in this area. It is of great interests to both physicists approaching this subject for the first time, as well as ... "
