Journal ArticleDOI
Ultra-high hole mobility exceeding one million in a strained germanium quantum well
A. Dobbie,Maksym Myronov,Robert H. Morris,A. H. A. Hassan,M. J. Prest,Vishal Shah,Evan H. C. Parker,Terry E. Whall,David R. Leadley +8 more
TL;DR: In this article, the authors reported a Hall mobility of one million in a germanium two-dimensional hole gas at a carrier sheet density of 3'×'1011'cm−2 at 12'K. This mobility is nearly an order of magnitude higher than any previously reported.
Journal ArticleDOI
Ultra high hole mobilities in a pure strained Ge quantum well
O. A. Mironov,A. H. A. Hassan,Richard J. H. Morris,A. Dobbie,M. Uhlarz,Daniel Chrastina,James P. Hague,S. Kiatgamolchai,Richard Beanland,S. Gabani,I. B. Berkutov,Manfred Helm,O. Drachenko,Maksym Myronov,David R. Leadley +14 more
TL;DR: In this article, the authors used maximum entropy-mobility spectrum analysis (ME-MSA) and Bryan's algorithm mobility spectrum (BAMS) analysis to determine hole gas drift mobility at low and room temperature.
Journal ArticleDOI
New RP‐CVD grown ultra‐high performance selectively B‐doped pure‐Ge 20 nm QWs on (100)Si as basis material for post‐Si CMOS technology
O. A. Mironov,A. H. A. Hassan,M. Uhlarz,S. Kiatgamolchai,A. Dobbie,Richard J. H. Morris,John E. Halpin,Stephen Rhead,Phil Allred,Maksym Myronov,S. Gabani,I. B. Berkutov,David R. Leadley +12 more
TL;DR: Magnetotransport studies at low and room temperature are presented for two-dimensional hole gases (2DHG) formed in fully strained germanium (sGe) quantum wells (QW) as discussed by the authors.
Journal ArticleDOI
An origin behind Rashba spin splitting within inverted doped sGe heterostructures
TL;DR: In this paper, the authors demonstrate why cubic Rashba spin splitting is observed within inverted doped strained germanium (sGe) hetrostructures and identify the source of spin splitting from a combination of ultra low energy secondary ion mass spectrometry analysis and subsequent band structure modelling using Nextnano3.
Proceedings ArticleDOI
Structural and electrical characterization of SiGe heterostructures containing a pure Ge strained quantum well
A. H. A. Hassan,O. A. Mironov,A. Dobbie,J. H. Morris,S. Gabani,Alexander Feher,E. Cizmar,V. V. Andrievskii,I. B. Berkutov +8 more
TL;DR: In this paper, structural characterization and magneto-transport properties of the two dimensional hole gas in strained germanium heterostructures were presented, along with the lowest value of effective mass to date, using Schubnikov de Haas oscillations.
