The recent development in understanding the structures, relative stability, and electronic properties of large fullerenes is reviewed. We describe an efficient scheme to generate the ground-state networks for fullerene clusters. Combining this scheme with quantum-mechanical total-energy calculations, the ground-state structures of fullerenes ranging from C 20 to C 100 have been studied. Fullerenes of sizes 60, 70, and 84 are found to be energetically more stable than their neighbors. In addition to the energies, the fragmentation stability and the chemical reactivity of the clusters are shown to be important in determining the abundance of fullerene isomers.

Представлены результаты моделирования пространственной структуры и электронных свойств кластеров MeGe16 - и MeGe20 - (Me = Sc, Y, Lu). Рассматривается возможность синтеза  пуллереноподобных кластеров и кластеров с другими типами замкнутых структур. Проведены сравнительные расчеты в рамках теории функционала плотности с использованием базиса SDD и трех различных потенциалов – B3LYP, B3PW91 и PBEPBE. Анализируется влияние выбора потенциала на результаты моделирования пространственной структуры кластеров и их электронного спектра. Оценка адекватности теоретических методов проводится путем сравнения рассчитанных электронных спектров с экспериментальными результатами по фотоэлектронной спектроскопии кластеров.     REFERENCES Kroto H.

In AA-stacked twisted bilayer graphene, the lower energy bands become completely flat when the twist angle passes through certain specific values: the so-called “magic angles”. The Dirac peak appears at zero energy due to the flattening of these bands when the twist angle is sufficiently small [1-3]. When a constant perpendicular magnetic field is applied, Landau levels start appearing as expected [5]. We used the Kernel Polynomial Method (KPM) [6] as implemented in KITE [7] to study the optical and electronic properties of these systems. The aim of this work is to analyze how the features of these quantities change with the twist angle in the presence of an uniform magnetic field.
