A computational study of van der Waals tunnel transistors: Fundamental aspects and design challenges
Cao, Jiang; Logoteta, Demetrio; Özkaya, Özkaya; Biel, Blanca; Cresti, Alessandro; Pala, Marco; Esseni, David (Institute of Electrical and Electronics Engineers Inc., 2015)We propose a model Hamiltonian for van der Waals tunnel transistors relying on a few physical parameters that we calibrate against DFT band structure calculations. This approach allowed us to develop a fully three-dimensional ... -
MXene-based Ti2C/Ta2C lateral heterostructure: an intrinsic room temperature ferromagnetic material with large magnetic anisotropy
Özcan Özkaya, Sibel; Biel, Blanca (Royal Society of Chemistry, 2023)Two-dimensional (2D) lateral heterostructures (LH) combining Ti2C and Ta2C MXenes were investigated by means of first-principles calculations. Our structural and elastic properties calculations show that the lateral Ti2C/Ta2C ... -
Operation and design of van der waals tunnel transistors: a 3-d quantum transport study
Cao, Jiang; Logoteta, Demetrio; Özkaya, Sibel; Biel, Blanca; Cresti, Alessandro; Pala, Marco; Esseni, David (IEEE, 2016)We propose a model Hamiltonian for van der Waals tunnel transistors (vdW-TFETs) relying on few physical parameters calibrated against density functional theory (DFT) band structure calculations. Based on this model, we ... -
Point-like vacancies in two-dimensional transition metal dichalcogenides
Özcan, Sibel; Gallardo, Aurelio; Biel, Blanca (Institute of Physics, 2024)his study explores the realm of two-dimensional transition metal dichalcogenides (TMDs), examining some of the most prevalent defects. Employing density functional theory, we scrutinize three common defect types across ...
